NHC Initiates Advisories on Potential Tropical Cyclone Two

The National Hurricane Center (NHC) initiated advisories on Potential Tropical Cyclone Two on Wednesday morning.  NHC initiated the advisories in order to be able to issue watches for a portion of the coast of Louisiana.  At 11:00 a.m. EDT on Wednesday the center of Potential Tropical Cyclone Two was located at latitude 28.5°N and longitude 86.4°W which put it about 170 miles (270 km) east-southeast of the Mouth of the Mississippi River.  It was moving toward the west-southwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h).  The minimum surface pressure was 1011 mb.  A Tropical Storm Watch was issued for the portion of the coast from the Mouth of the Mississippi River to Morgan City, Louisiana.

The circulation around Potential Tropical Cyclone Two was not well organized.  There was a large, but relatively weak circulation near the surface.  There was not a well defined center of circulation near the surface.  There was a stronger counterclockwise circulation between about 10,000 feet (3000 meters) and 25,000 feet (7600 meters) above the surface, which was located above the southwestern part of the surface circulation.  Many of the stronger thunderstorms were occurring in bands on the northern and western sides of the circulation above the surface.  There were fewer thunderstorms in the eastern side of the larger, surface circulation.

Potential Tropical Cyclone Two will move through an environment very favorable for development and intensification.  It will move over water where the Sea Surface Temperature is near 30°C.  The system will move through a region where the upper level winds are weak and there will be little vertical wind shear.  It is likely that a center of circulation will form at the surface underneath the counterclockwise circulation above the surface.  Potential Tropical Cyclone Two will strengthen slowly until the surface center is underneath the center higher in the atmosphere.  After the circulation becomes aligned vertically, the system could strengthen more rapidly.  Potential Tropical Cyclone Two is likely to become a hurricane within 48 to 60 hours.

Potential Tropical Cyclone Two will move south of a ridge over the southeastern U.S.  The ridge will steer Potential Tropical Cyclone Two toward the southwest.  It will move more toward the west on Thursday and then turn back more toward the northwest on Friday when it nears the western end of the ridge.  There will be significant uncertainty about the future track of the system until a well defined center of circulation forms at the surface.  On its anticipated track the center of Tropical Cyclone Two could approach the coast of Louisiana and northeast Texas on Friday.  Hurricane Watches and Warnings are likely to be issued for portions of the coast later this week.

Potential Tropical Cyclone Two presents a wide range of hazards.  It will bring hurricane force winds to portions of Louisiana and Texas and it will disrupt operations of offshore facilities in the northwestern Gulf of Mexico.  After the center of the system moves west of New Orleans, southerly winds will force water into the Mouth of the Mississippi River.  The level of the Mississippi River around New Orleans is already near flood stage and any additional rise in the water level could cause serious flooding around the city.  If Potential Tropical Cyclone Two strengthens into a hurricane, as expected, it will cause a significant storm near where the center makes landfall.  The system also has the potential to drop heavy rain and flooding could occur when it moves inland.

Potential Tropical Development Over Northern Gulf of Mexico

The potential exists for the development of a tropical cyclone over the northern Gulf of Mexico this week.  A low pressure system was over Georgia on Monday afternoon.  The low was drifting slowly southward, but it was forecast to move more toward the south-southwest during the next two days.  Several numerical models were predicting that the low pressure system would strengthen into a tropical depression or a tropical storm after it moves over the northern Gulf of Mexico later this week.  The National Hurricane Center was indicating that the low pressure system, currently designated as Invest 92L, had a 30% probability of developing into a tropical cyclone during the next two days and an 80% probability of developing into a tropical cyclone during the next five days.

The low pressure system exhibited a surface circulation on Monday afternoon, but the wind speed was near 15 m.p.h. (25 km/h).  Bands of showers and thunderstorms formed during the daytime heating over land, but they weakened at night.  There was also a counterclockwise rotation in the lower and middle troposphere which may have been the remnants of a mesoscale convective vortex (MCV), which developed over the Middle Mississippi River Valley a few days ago.  The low was not generating upper level divergence on Monday afternoon.

If the low pressure system does move over the northern Gulf of Mexico on Tuesday or Wednesday, it will move into an environment more favorable for the development of a tropical depression.  The Sea Surface Temperature of the water in the northeastern Gulf of Mexico is near 30°C.  The low pressure system will move southeast of an upper level ridge over the southern U.S.  The ridge will produce northeasterly winds, but the winds will be relatively weak and the vertical wind shear will not be too strong.  More thunderstorms are likely to develop when the low pressure system moves over the warm water.  If those thunderstorms generate upper level divergence that pumps mass away, then the surface pressure will decrease and a tropical depression will form.

The upper level ridge is forecast to steer the low pressure system toward the west after it moves over the Gulf of Mexico later this week.  On its anticipated track the low pressure system will move slowly toward the coast of Louisiana and Texas.  The future intensity of the system will be determined by how far the system moves into the Gulf of Mexico.  If the low pressure system takes a track along or near the north coast of the Gulf of Mexico, then it will likely become a tropical depression or a weak tropical storm.  Even if the low only strengthens into a tropical depression, it could drop heavy rain and the potential for flooding exists along the northern Gulf Coast.  If the low pressure system moves farther out into the Gulf of Mexico and remains over warm water for a longer period, then it might intensify into a hurricane.  Residents along the Gulf Coast should monitor this system carefully.

Tropical Storm Sergio Brings Rain to Baja California

Tropical Storm Sergio brought rain to Baja California on Friday morning.  At 8:00 a.m. EDT on Friday the center of Tropical Storm Sergio was located at latitude 26.8°N and longitude 112.8°W which put it about 45 miles (75 km) southwest of Santa Rosalia, Mexico.  Sergio was moving toward the northeast at 24 m.p.h. (39 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 998 mb.

A Tropical Storm Warning was in effect for the west coast of Baja California from Punta Eugenia to Cabo San Lazaro, Mexico.  A Tropical Storm Warning was also in effect for the east coast of Baja California from Bahia San Juan Bautista to Mulege, Mexico.

Tropical Storm Sergio was weakening as it approached Baja California.  An upper level trough was producing strong southwesterly winds which were blowing across the top of Tropical Storm Sergio.  Those winds were causing strong vertical wind shear and they were in the process of blowing the middle and upper portions of the circulation northeast of the surface circulation.  A combination of strong vertical wind shear and passage over mountains on Baja California will case Tropical Storm Sergio to weaken quickly.

Tropical Storm Sergio will drop locally heavy rain over parts of Baja California and northern Mexico.  The greatest risk from Sergio is the potential for the locally heavy rain to cause flash floods.  The remnants of Tropical Storm Sergio could enhance rainfall in southeastern New Mexico, West Texas, and Oklahoma during the weekend.

Tropical Storm Sergio Cause Warnings for Baja California

Tropical Storm Sergio prompted the issuance of warnings and watches for parts of Baja California on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Sergio was located at latitude 20.0°N and longitude 121.5°W which put it about 770 miles (1240 km) west-southwest of the southern tip of Baja California.  Sergio was moving toward the northeast at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 992 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Punta Eugenia to Cabo San Lazaro, Mexico.  A Tropical Storm Watch was in effect for the portion of the coast from Bahia San Juan Bautista to San Evaristo, Mexico.

Tropical Storm Sergio weakened slightly on Wednesday, but the structure of the circulation remained well organized.  A large clear area at the center of circulation was the remnant of the eye that existed when Sergio was a hurricane.  The remnant of the eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Several thin bands of showers and thunderstorms were revolving around the core of Tropical Storm Sergio.  Winds to tropical storm force extended out about 140 miles (225 km) from the center of Sergio.

Tropical Storm Sergio will move over cooler water on Thursday.  An upper level trough west of California will produce southwesterly winds which will blow toward the top of the circulation.  Those winds will cause moderate vertical wind shear.  The combination of cooler water and more wind shear will cause Tropical Storm Sergio to weaken slowly.

The upper level trough will steer Tropical Storm Sergio toward the northeast during the next several days.  On its anticipated track Tropical Storm Sergio will reach Baja California on Thursday night.  Sergio will bring gusty winds, but locally heavy rain is a greater risk because heavy rain could cause flash floods.

Hurricane Sergio Turns Back Toward Baja California

Hurricane Sergio turned back toward Baja California on Tuesday morning.  At 11:00 a.m. EDT on Tuesday the center of Hurricane Sergio was located at latitude 16.6°N and longitude 127.4°W which put it about 1215 miles (1960 km) west-southwest of the southern tip of Baja California.  Sergio was moving toward the northeast at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (155 km/h).  The minimum surface pressure was 982 mb.

Hurricane Sergio was slowly weakening.  It appeared that cooler, drier air was entering the western half of the circulation.  Sergio has been moving slowly and its winds may have mixed some cooler water to the surface of the ocean.  Rainbands on the western side of Sergio consisted primarily of showers and lower clouds and thunderstorms in western side of the eyewall were weakening.  Stronger thunderstorms were still occurring in the eastern side of the eyewall and that was where the strongest winds were occurring.  Some strong storms were also occurring in a band southeast of the center of circulation.

Hurricane Sergio will move through an environment that will cause it to continue to weaken slowly.  Sergio is currently over water where the Sea Surface Temperature is near 27°C, but it will move over cooler water in a day or so.  An upper level trough centered west of California will produce southwesterly winds which will cause more vertical wind shear.  The combination of cooler water and more wind shear will cause Hurricane Sergio to weaken to a tropical storm within the next 24 to 36 hours.

The upper level trough will steer Hurricane Sergio toward the northeast during the next several days.  On its anticipated track Sergio could approach central Baja California on Thursday night.  It will likely be a tropical storm at that time.  Tropical Storm Watches could be issued for parts of the coast later today or on Wednesday.  Sergio will bring gusty winds and it will drop locally heavy rain.  The rain could cause flash flooding.  Sergio could also bring some rain to New Mexico and west Texas during the weekend.

Hurricane Bud Weakens, Watch Issued for Baja California

Hurricane Bud weakened significantly on Tuesday, but it prompted the issuance of a Tropical Storm Watch for the southern portion of Baja California.  At 11:00 p.m. EDT on Tuesday the center of Hurricane Bud was located at latitude 18.7°N and longitude 108.6°W which put it about 300 miles (485 km) south-southeast of Cabo San Lucas, Mexico.  Bud was moving toward the north-northwest at 3 m.p.h. (5 km/h).  The maximum sustained wind speed was 90 m.p.h. (150 km/h) and there were wind gusts to 105 m.p.h. (170 km/h).  The minimum surface pressure was 973 mb.  The government of Mexico issued a Tropical Storm Watch for the portion of the coast from Santa Fe to La Paz, Mexico including Cabo San Lucas.

Hurricane Bud weakened to a Category 1 hurricane on the Saffir-Simpson Scale on Tuesday.  The center of Hurricane Bud was over water where the Sea Surface Temperature was near 27°C, but much of the northern half of the circulation was over cooler water.  The slow movement of Bud may have also allowed the winds to mix cooler water to the surface.  Thunderstorms were not as tall and the bands in the northern half of the circulation consisted primarily of showers and low clouds.  The stronger thunderstorms were occurring mainly south and east of the center of Hurricane Bud.

Hurricane Bud is forecast to spin down slowly during the next several days.  Cooler water at the surface of the ocean is not likely to supply sufficient energy to maintain the circulation.  The upper level winds are weak and there is little vertical wind shear, but the lack of shear will be less important than effects of the cooler water.  The lack of stronger thunderstorms in the northern half of the circulation will limit the downdrafts that could transport stronger winds to the surface.  Hurricane Bud could weaken to a tropical storm on Wednesday if new thunderstorms do not form in the core of the circulation.

A ridge in the middle troposphere over the southwestern U.S. almost blocked the forward motion of Hurricane Bud on Tuesday.  Bud moved slowly toward the north-northwest.  A slow motion toward the north-northwest is forecast to continue for another 24 to 36 hours.  After that time a trough over the Pacific Ocean is forecast to push the ridge eastward.  When the trough approaches, stronger southerly winds will steer Bud northward more quickly.  On its anticipated track Bud is forecast to approach the southern tip of Baja California in 36 to 48 hours.

Hurricane Bud is likely to be a tropical storm when it nears Baja California.  Bud will bring gusty winds, but the bigger risk will be locally heavy rain.  Heavy rain falling on steep terrain could cause flash floods.  Bud or its remnants could also bring rain to parts of the southwestern U.S.

Cyclone Likely to Form Over Gulf of Mexico

A cyclone is likely to form over the Gulf of Mexico during the upcoming weekend.  A broad area of low pressure at the surface is currently centered over the Yucatan Peninsula.  The area of low pressure is currently designated as Invest 90L.  The circulation around the low pressure system is not well organized at the current time.  The center of the surface low is over the Yucatan Peninsula.  Showers and lower clouds are occurring near the center of the low.  Stronger thunderstorms are occurring on the eastern side of the low over the northwestern Caribbean Sea.  Sustained winds of 20 m.p.h. to 30 m.p.h. (30 km/h to 50 km/h) were blowing across the northwestern Caribbean Sea.  The winds were weaker over land near the center of circulation.

An upper level trough over the Gulf of Mexico was producing strong westerly winds which were blowing over the top of the surface low.  Those winds were causing strong vertical wind shear and the wind shear was one of the reasons why the stronger thunderstorms were occurring east of the center of circulation.  Sinking motion in the western portion of the upper level trough was bringing drier air to the surface and the drier air was inhibiting the formation of thunderstorms in the western side of the surface low.

The National Hurricane Center (NHC) indicated in a Special Tropical Weather Outlook at 2:00 p.m. EDT on Thursday that there is a 70% probability of the formation of a subtropical or tropical depression during the next 48 hours.  NHC has tentatively tasked a reconnaissance aircraft to investigate the low pressure system on Friday afternoon if necessary.

The wind speeds are slower near the axis of the upper level trough.  If the surface low pressure system moves under the axis of the upper level trough, then there would be less vertical wind shear and a cyclone could form.  If thunderstorms develop near the center of circulation after the center moves over the northwestern Caribbean Sea or southeastern Gulf of Mexico, then NHC would likely designate the system as a tropical depression.  If the thunderstorms develop farther away from the center of circulation and the circulation does not exhibit a tropical appearance, then NHC could classify the system as a subtropical depression.  NHC would issue advisories on the cyclone even if it is designated a subtropical depression.

There is a strong high pressure system over the Atlantic Ocean and the high is likely to steer the surface low toward the north.  The Sea Surface Temperature of the water in the southeastern Gulf of Mexico is near 27°C.  So, there is enough energy to support the formation of a tropical cyclone.  Most of the stronger thunderstorms are likely to continue to form in the eastern side of the circulation because of the vertical wind shear and drier air to the northwest of the surface low.  The low pressure system could slowly organize into a tropical storm during the weekend.

Heavy rain and the potential for flooding are the greatest risks with this low pressure system.  There will be some storm surge along the eastern and northern coasts of the Gulf of Mexico as counterclockwise rotation around the low blows water toward the shore.

Hurricane Nate Speeds Toward Gulf Coast

Strengthening Hurricane Nate sped toward the central Gulf Coast on Saturday.  At 11:00 a.m. EDT on Saturday the center of Hurricane Nate was located at latitude 26.6°N and longitude 88.4°W which put it about 265 miles (425 km) south of Biloxi, Mississippi.  Nate was moving toward the north-northwest at 26 m.p.h. (43 km/h).  The maximum sustained wind speed was 90 m.p.h. (150 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 984 mb.

A Hurricane Warning was in effect for the portion of the coast from Grand Isle, Louisiana to the Alabama/Florida border including New Orleans and Lake Pontchartrain.  A Hurricane Watch was in effect for the portion of the coast from the Alabama/Florida border to the Okaloosa/Walton County line and from Grand Isle to Morgan City, Louisiana.  A Tropical Storm Warning was in effect for the portion of the coast from the Alabama/Florida border to Indian Pass, Florida and from Grand Isle to Morgan City.  A Tropical Storm Watch was in effect for the portion of the coast from Morgan City to Intracoastal City, Louisiana.

Hurricane Nate strengthened on Saturday as it moved over the warm water in the Gulf of Mexico.  An eye with a diameter of 30 miles (50 km) began to form at the center of circulation.  A ring of thunderstorms around the eye was generating strong upper level divergence which pumped mass away from Hurricane Nate.  The strongest winds were occurring in the eastern side of the circulation.  Winds to hurricane force extended out about 35 miles (55 km) east of the center of circulation.  Winds to tropical storm force extend out about 120 miles (195 km) east of the center, but they only extend out about 60 miles (95 km) to the west of the center.

The Hurricane Intensity Index (HII) for Hurricane Nate is 13.9.  The Hurricane Size Index (HSI) is 7.7 and the Hurricane Wind Intensity Size Index (HWISI) is 21.6.

Hurricane Nate will continue to intensify during the next 12 hours until it makes landfall.  Nate will move over water where the Sea Surface Temperature is near 29°C.  An upper low over the western Gulf of Mexico is producing southerly winds which are blowing toward the top of the circulation.  However, there are also southerly winds in the lower levels of the atmosphere and as a result, there is not much vertical wind shear.  Hurricane Nate is likely to intensify to a Category 2 hurricane on the Saffir-Simpson Scale before it makes landfall.  There is a chance Hurricane Nate could intensify to Category 3 before landfall, if it continues to intensify rapidly.

The upper low and an upper level ridge east of Florida are combining to steer Hurricane Nate quickly toward the north-northwest and that motion is expected to continue for the next few hours.  An upper level trough over the Central U.S. will approach Nate on Saturday night as the hurricane nears the coast.  The trough will turn Hurricane Nate more toward the north as it reaches the coast.  The trough should steer Nate quickly toward the north-northeast after it makes landfall.  On its anticipated track the center of Hurricane Nate will pass near the mouth of the Mississippi River on Saturday evening.  The center of Nate will likely make landfall on the coast of Mississippi or near Mobile on Saturday night.

Hurricane Nate will be capable of causing regional serious damage when it makes landfall.  Nate will produce strong winds, especially in locations east of the track of the hurricane.  Nate will also be capable of producing a storm surge of 10 to 12 feet (3 to 4 meters) along the coast.  The surge will be higher in bays, inlets and mouths of rivers that funnel the water into specific areas.  Nate will also be capable of dropping heavy rain as it moves inland.

Stronger Tropical Storm Nate Speeds Toward Gulf of Mexico, Hurricane Warning for New Orleans

A stronger Tropical Storm Nate sped toward the Gulf of Mexico on Friday afternoon and a Hurricane Warning was issued for the city of New Orleans.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Nate was located at latitude 20.3°N and longitude 85.7°W which put it about 80 miles (125 km) east of Cozumel, Mexico and about 710 miles (1145 km) south-southeast of New Orleans, Louisiana.  Nate was moving toward the north-northwest at 21 m.p.h. (33 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 993 mb.

A Hurricane Warning was in effect for the portion of the coast from Grand Isle, Louisiana to the Alabama/Florida border including New Orleans and Lake Pontchartrain.  A Hurricane Watch was in effect for the portion of the coast from the Alabama/Florida border to the Okaloosa/Walton County line in Florida.  A Tropical Storm Warning was in effect for the portion of the coast from Grand Isle to Morgan City, Louisiana and from the Alabama/Florida border to the Okaloosa/Walton County line.  A Tropical Storm Watch was in effect from Morgan City to Intracoastal City, Lousiana and from the Okaloosa/Walton County line to Indian Pass, Florida.  A Hurricane Watch and a Tropical Storm Warning are in effect for the portion of the coast from Punta Herrero to Rio Lagartos, Mexico.  A Tropical Storm Warning is in effect for Pinar del Rio province in Cuba.  A Tropical Storm Watch is in effect for Isle of Youth province in Cuba.

The inner core of Tropical Storm Nate tightened up on Friday afternoon.  A primary rainband wrapped about three quarters of the way around the center of circulation.  There was an opening to the northeast of the center.  The rainband could develop into an eyewall if it wraps completely around the center of circulation.  Additional bands of showers and thunderstorms formed outside the core of Tropical Storm Nate.  Winds to tropical storm force extended out about 125 miles (200 km) to the east of the center of circulation.  The winds were weaker in the western half of the circulation.  Thunderstorms near the core began to generate stronger upper level divergence which was pumping out mass and the surface pressure decreased on Friday afternoon.

Tropical Storm Nate will move through an environment favorable for intensification on Saturday.  Nate will move over water where the Sea Surface Temperature is near 30°C.  An upper level low over the western Gulf of Mexico is producing southerly winds which are blowing toward the top of the circulation but the vertical wind shear is not too strong.  Tropical Storm Nate will become a hurricane over the Gulf of Mexico.  If an eyewall and an eye form, then Nate could have a period of rapid intensification.

The upper low over the western Gulf of Mexico and a ridge east of Florida are combining to steer Tropical Storm Nate toward the north-northwest and that general motion is expected to continue on Saturday.  An upper level trough approaching from the west will turn Nate toward the northeast when it nears the U.S.  On its anticipated track Tropical Storm Nate will pass near the northeastern end of the Yucatan peninsula and move into the Gulf of Mexico on Friday night.  Nate will approach southeastern Louisiana and Central Gulf Coast on Saturday night.

Nate will be a hurricane when it nears the U.S.  It will be capable of producing serious regional wind damage and power outages.  Nate could cause a storm surge of 10-12 feet (3 to 4 meters) near where the center makes landfall.  Nate could also drop locally heavy rain and cause fresh water flooding when it moves inland in the southern U.S.

Tropical Storm Nate Makes Landfall in Nicaragua

Tropical Depression Sixteen strengthened into Tropical Storm Nate and Nate made landfall on the coast of northeastern Nicaragua on Thursday morning.  At 2:00 p.m. EDT on Thursday the center of Tropical Storm Nate was located at latitude 14.5°N and longitude 84.0°W which put it about 50 miles (80 km) south-southwest of Puerto Lempira, Honduras.  Nate was moving toward the northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1001 mb.

A Hurricane Watch was in effect for the portion of the coast from Punta Herrero to Rio Lagartos, Mexico.  A Tropical Storm Warning is also in effect from Punta Herrero to Rio Lagartos.  A Tropical Storm Warning is in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to Punta Castilla, Honduras.

The center of Tropical Depression Sixteen strengthened on Thursday morning before it made landfall in Nicaragua and the National Hurricane Center designated the system as Tropical Storm Nate.  Showers and thunderstorms continue to develop near the center of circulation even though it is moving across northeastern Nicaragua.  The winds to tropical storm force are occurring in bands of showers and storms east of the center over the Caribbean Sea.  The winds are weaker in the portions of the circulation that are over land.

Tropical Storm Nate will not strengthen while the center is over land.  Nate will move into a favorable environment when it moves over the northwestern Caribbean Sea on Friday.  The Sea Surface Temperature will be near 30°C.  An upper level low will cause southerly winds to blow toward the top of the circulation, but the vertical wind shear is not likely to be strong enough to prevent intensification.  It could take a few hours for the inner core of the circulation to reorganize after it moves back over water.  Once the inner core reorganizes, then a period of rapid intensification could occur.  Nate could become a hurricane over the northwest Caribbean Sea or southern Gulf of Mexico.

An upper level low west of Florida will drift westward over the Gulf of Mexico.  The upper low and an upper level ridge east of Florida will combine to steer Tropical Storm Nate toward the north-northwest.  On its anticipated track Tropical Storm Nate will emerge over the northwestern Caribbean Sea on Friday.  Nate could be near the Yucatan peninsula on Friday night and it could move into the Gulf of Mexico on Saturday.  Nate could approach the northern Gulf Coast on Saturday night or Sunday morning.

Tropical Storm Nate is dropping heavy rain on parts of Nicaragua and Honduras.  There is the potential for flooding in those areas.  Nate is likely to be a hurricane when it approaches the Gulf Coast.  It will be capable of causing wind damage, a storm surge and locally heavy rain.
