System Could Bring Heavy Rain to Southeast U.S.

A weather system over the southeastern Gulf of Mexico could bring heavy rain to the southeastern U.S. this week.  An upper level low over the eastern Gulf of Mexico could transfer enough kinetic energy down to the lower troposphere to spin up a low at the surface.  Air flowing around the eastern side of the low is contributing to upper level divergence over Florida.  The divergence enhanced rising motion over Florida and rain fell over parts of the southern and central portions of that state.

The weather system is forecast to move slowly northward during the next several days.  The Sea Surface Temperatures in the southeastern Gulf of Mexico are 24°C to 26°C.  There is enough energy in the upper levels of the water to support the formation of a tropical cyclone.  The upper level low will create southerly winds which will cause moderate vertical wind shear.  The shear will inhibit development, although those winds could contribute to upper level divergence to the east of the weather system.  Upper level divergence could allow the surface pressure to decrease and a low pressure system could form at the surface.  The National Hurricane Center (NHC) issued a special Tropical Weather Outlook on Sunday afternoon on the weather system.  NHC indicated the probability was 40% that a tropical or subtropical cyclone could form during the next five days.

Guidance from numerical models suggest that the weather system will move slowly northward over the eastern Gulf of Mexico during the next few days.  Counterclockwise rotation around the low will transport moist air northward on the eastern side of the low.  The moist air combined with upper level divergence will create the potential for locally heavy rainfall over the southeastern U.S.  Heavy rain could result in floods in some locations.

System to Bring Wind, Rain to Bahamas and South Florida

A complex weather system near the Bahamas is forecast to move westward and it will bring gusty winds and locally heavy rain to parts of the Bahamas and South Florida during the weekend.  The circulation is strongest in the middle and upper troposphere.  An upper level low is centered near the Bahamas.  Showers and thunderstorms are occurring north and east of the upper low.  There is not a distinct center of circulation in the lower troposphere or at the surface.  There is a small upper level ridge to the east of the upper low and the ridge is producing some upper level divergence which is pumping mass away to the east of the system.

The system will move through an environment that is only marginally favorable for the development of a tropical cyclone.  It will move over water where the Sea Surface Temperature is near 26°C.  So, there is potentially enough energy in the upper ocean to support the development of a minimal tropical cyclone.  The upper low and the ridge to the east are southerly winds near the Bahamas and westerly winds southeast of the Bahamas.  Those winds are causing strong vertical wind shear.  The winds are weaker near the center of the upper low, but there are no thunderstorms in that region at the current time.  If a surface low were to develop under the center of the upper low, then there would be the possibility of some slow development.  A second, possible scenario is that a subtropical cyclone develops north and east of the upper low where the showers and thunderstorms are forming.

The National Hurricane Center (NHC) issued a special Tropical Weather Outlook on this system at 10:45 a.m. EDT on Friday.  NHC indicated that “no significant development” is expected and it gives a 0% probability of the formation of a tropical cyclone.

The upper level low is forecast to move south-southwest over the northwestern Caribbean Sea during the next 72 hours.  The surface and lower parts of the system are forecast to move across the Bahamas toward South Florida during the weekend.  Since the showers and thunderstorms are occurring north and east of the upper low, this could bring gusty winds and locally heavy rain to parts of the Bahamas and South Florida during the weekend.  Some of the humid air on the northeastern periphery of the system could be pulled toward the Carolinas ahead of an approaching cold front.  The moist air could enhance rainfall in eastern South Carolina and eastern North Carolina when the cold front moves through those places and lifts the air.

Hurricane Maria Weakens As It Moves Over Jose’s Cold Wake

Hurricane Maria weakened on Sunday as it moved over an area of cooler water mixed to the surface by Hurricane Jose last week.  At 11:00 p.m. EDT on Sunday the center of Hurricane Maria was located at latitude 30.0°N and longitude 73.0°W which put it about 385 miles (625 km) south-southeast of Cape Hatteras, North Carolina.  Maria was moving toward the north at 8 m.p.h. (13 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 950 mb.

A Tropical Storm Watch was in effect for the portion of the coast from Surf City, North Carolina to the North Carolina/Virginia border including Albemarle and Pamlico Sounds.

Hurricane Maria is moving over an area traversed by Hurricane Jose a week ago.  The winds of Jose mixed cooler water to the surface.  The region of cooler water is sometimes called the cold wake because it is left behind after a hurricane passes over a section of the ocean.  Observations from a NOAA research aircraft indicate that the Sea Surface Temperatures beneath Hurricane Maria are 24°C to 25°C.  There is not enough energy in the upper ocean to support a major hurricane and the circulation of Hurricane Maria has weakened during the past 24 hours.  The clouds around the eye and in the rainbands are not as tall.

Even though the upper level winds are not too strong and there is not much vertical wind shear, Hurricane Maria is unlikely to intensify.  Maria will continue to move over cooler water mixed to the surface by Jose.  Maria is likely to continue to weaken slowly during the next day or two.  Maria is a large hurricane and winds to tropical storm force extend out about 230 miles (370 km) from the center.

Maria is moving around the western end of subtropical high over the Atlantic Ocean.  The high is steering Maria toward the north and that general motion is expected to continue for several more days.  On its anticipated track Hurricane Maria would be southeast of Cape Hatteras on Tuesday night.  When Maria gets closer to the Outer Banks of North Carolina, the hurricane will reach the westerly flow in middle latitudes.  Those westerly winds are forecast to steer Hurricane Maria toward the east later this week.

Because of the large size of Hurricane Maria’s circulation, winds to tropical storm force could be near the Outer Banks even if the center of Maria remains offshore.  Maria will also generate large waves and significant beach erosion could occur.

Hurricane Maria Pulls Away from the Turks and Caicos

Hurricane Maria pulled away slowly from the Turks and Caicos on Friday.  At 5:00 p.m. EDT on Friday the center of Hurricane Maria was located at latitude 23.3°N and longitude 71.4°W which put it about 395 miles (635 km) east-southeast of Nassau, Bahamas.  Maria was moving toward the north-northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 125 m.p.h. (205 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 959 mb.

Tropical Storm Warnings were in effect for the Turks and Caicos, Southeastern Bahamas and Central Bahamas.

The structure of Hurricane Maria did not change much on Friday.  An eye continued to mark the center of circulation.  A nearly complete ring of thunderstorms surrounded the eye.  The strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms revolved around the core of Hurricane Maria.  There were more showers and thunderstorms in the northern half of the circulation.  Winds to hurricane force extended out about 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out about 160 miles (260 km) from the center.

Hurricane Maria will move through an environment that is somewhat favorable for hurricanes.  Maria will move over water where the Sea Surface Temperature is near 29°C.  An upper level trough over the southeastern U.S. is producing southwesterly winds which are blowing toward the top of the circulation.  Those winds are not producing strong vertical wind shear, but they could impede upper level divergence to the west of Hurricane Maria.  Hurricane Maria could maintain its intensity for another day or two unless the vertical shear increases. If the shear increases, then Maria will start to weaken.

Hurricane Maria has reached the western end of the subtropical high pressure system over the Atlantic Ocean.  The high is steering Maria toward the north-northwest.  A general north-northwesterly motion is expected to continue for several more days.  On its anticipated track the core of Hurricane Maria will pass east of the Bahamas.

Hurricane Jose Turns Back Toward U.S.

Hurricane Jose completed the long slow clockwise loop it made this week over the Atlantic Ocean and it turned back toward the U.S.  At 5:00 p.m. EDT on Friday the center of Hurricane Jose was located at latitude 27.1°N and longitude 70.3°W which put it about 640 miles (1025 km) southeast of Cape Hatteras, North Carolina.  Jose was moving toward the northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 983 mb.

An eye appeared to be forming at the center of Hurricane Jose as the primary rainband wrapped around the eastern and northern portions of the developing eye.  The strongest winds were occurring in that rainband.  Additional bands of showers and thunderstorms were revolving around the eastern half of the circulation.  There were fewer showers and thunderstorms in the western half of the circulation.

Hurricane Jose is moving over the part of the Atlantic Ocean that the hurricane traversed several days ago.  So, Jose is moving over cooler water that it mixed to the surface when it moved over the area the first time.  Hurricane Jose will soon move northwest of its previous track and it will move over water where the Sea Surface Temperature is near 30°C.  The upper level winds will be weak and there will be little vertical wind shear.  Hurricane Jose will strengthen during the weekend and it could intensify rapidly once the eye and eyewall are fully formed.

After a few days of weak steering currents the large subtropical high pressure system over the Atlantic Ocean has started to steer Hurricane Jose toward the northwest.  A general northwesterly motion is forecast to continue for another 24 to 36 hours.  At that time Jose will reach the western end of the high and it will turn more toward the north.  On its anticipated track Hurricane Jose could be near the Outer Banks of North Carolina in two or three days.  It is still too early to know if the center of Hurricane Jose will move into the U.S.

Hurricane Jose Makes Loop East of the Bahamas

Hurricane Jose made a slow clockwise loop east of the Bahamas during the past several days.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Jose was located at latitude 25.2°N and longitude 66.0°W which put it about 935 miles (1510 km) east of Nassau, Bahamas.  Jose was moving toward the west at 3 m.p.h. (5 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 985 mb.

Hurricane Jose was in an area of weaker winds between an upper level ridge to the west and an upper level trough to the east.  The weaker steering winds pushed Jose around a slow clockwise loop.  The ridge is forecast to move north of Jose on Thursday and it should steer the hurricane toward the west.  The ridge is forecast to move east of Jose on Friday and the hurricane is expected to start moving more toward the north.

Hurricane Jose has been moving through an environment that was somewhat unfavorable for intensification.  Jose was moving over water where the Sea Surface Temperature was near 29°C.  However, the upper level ridge was producing northerly winds which were causing moderate vertical wind shear.  Hurricane Jose maintained its intensity despite the moderate shear, although there were fewer showers and thunderstorms in western half of the circulation.  The wind shear could decrease as the upper level ridge moves north of Jose and the hurricane could strengthen.

It is still too early to know if Hurricane Jose will have much of an impact on the U.S.  Most of the guidance from numerical models keeps Jose out over the Atlantic Ocean, but its actual track will depend on where and when the clockwise loop ends.

Tropical Storm Irma Still Bringing Gusty Winds and Storm Surges to Southeast U.S.

Tropical Storm Irma was still bringing gusty winds, locally heavy rain and storm surges to parts of the Southeastern U.S. on Monday afternoon.  Gusty winds were blowing down trees and bringing down power lines in parts of Florida, Georgia, South Carolina and North Carolina.  Locally heavy rainfall resulted in the issuance of Flood Watches and Warnings for portions of those states.  Strong winds were blowing water toward the coast in northeastern Florida, Georgia and South Carolina.  Storm surges caused flooding in Jacksonville, Florida and Savannah, Georgia.  The water level at Charleston, South Carolina was higher than it was during Hurricane Matthew in 2016.

At 5:00 p.m. EDT on Monday the center of Tropical Storm Irma was located at latitude 31.5°N and longitude 84.0°W which put it about 10 miles (15 km) east of Albany, Georgia.  Irma was moving toward the north-northwest at 17 m.p.h.  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 985 mb.

A Tropical Storm Warning remained in effect for the portion of the coast from Altamaha Sound to South Santee River.

The structure of Tropical Storm Irma evolved as it moved further inland.  Drier air wrapped around the  western side of the circulation.  Convergence between a large surface high north of Irma and the tropical storm produced heavy rain northeast of the center of circulation.  The heaviest rain fell over Georgia, South Carolina and the western half of North Carolina.  The northern edge of the rain shield was moving over Tennessee and southeast Kentucky.  The pressure difference between the high and Irma also generated strong winds in the eastern half of Irma’s circulation.  Those strong winds pushed water toward the coast in northern Florida, Georgia and South Carolina.  The wind caused storm surges of up to 10 feet (3 meters) in some locations.  Water was reported in parts of downtown Jacksonville, Florida and Charleston, South Carolina.

Tropical Storm Irma will continue to move toward the north-northwest and weaken.  The circulation of Irma is very large, and it will take a few more days to spin completely.  There could be stronger winds in the high elevations of Appalachian Mountains.  Locally heavy rain could also create the potential for floods in some valleys.  The storm surges along the coast should gradually subside as the wind speeds decrease.

Elsewhere, Hurricane Jose was moving northward east of the Bahamas.  At 5:00 p.m. EDT on Monday the center of Hurricane Jose was located at latitude 31.5°N and longitude 84.0°W which put it about 555 miles (895 km) east of Nassau, Bahamas.  Jose was moving toward the north at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 973 mb.  Hurricane Jose is forecast to make a slow clockwise loop this week.  On it anticipated track Hurricane Jose could still be east of the Bahamas at the end of the week.

Hurricane Irma Makes Landfall on Marco Island, Florida

The center of Hurricane Irma made landfall on the coast at Marco Island, Florida on Sunday afternoon.  The Marco Island Emergency Operations Center reported a wind gust to 135 m.p.h. (217 km/h) when the northern portion of the eyewall passed over.  The airport at Naples, Florida reported sustained winds to 88 m.p.h. (142 km/h) and wind gusts to 135 m.p.h. (217 km/h).

At 5:00 p.m. EDT on Sunday the center of Hurricane Irma was located at latitude 26.2°N and longitude 81.8°W which put it about 5 miles (10 km) north of Naples, Florida.  Irma was moving toward the north at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 130 m.p.h. (210 km/h).  The minimum surface pressure was 938 mb.

A Hurricane Warning was in effect for the portion of the coast from Fernandina Beach to Indian Pass, Florida including the Florida Keys and Lake Okeechobee.  A Hurricane Watch was in effect from Fernandina Beach, Florida to Edisto Beach, South Carolina.  A Tropical Storm Warning was in effect for the portion of the coast from Fernandina Beach, Florida to the South Santee River, South Carolina and from Indian Pass, Florida to the Okaloosa/Walton County line.  A Tropical Storm Watch was in effect for Bimini and Grand Bahama Island.

The intensity of Hurricane Irma decreased gradually on Sunday.  The hurricane began to pull in some drier air over the southeastern U.S. into the west side of the circulation.  In addition an upper level trough over the eastern U.S. caused an increase in the vertical wind shear.  The drier air and increased shear also produced a more asymmetrical wind field around Hurricane Irma.  The area of stronger winds was much larger in the eastern half of the circulation than it was on the western half of the circulation.  Winds to hurricane force extended out 80 miles (130 km) from the center of circulation.  Winds to tropical storm force extended out about 220 miles (350 km) from the center.

Hurricane Irma will gradually weaken as it moves northward over Florida.  Irma is a large hurricane and it will spin down slowly.  Hurricane Irma will move steadily northward.  Irma is forecast to still be a hurricane when the center moves near Tampa and Central Florida.  Hurricane Irma is capable of causing widespread significant wind damage.  Isolated tornadoes could develop in thunderstorms in the outer rainbands.  Hurricane Irma will produce storm surges over a long section of the coast.  There was not much surge on the west coast of Florida on Sunday afternoon, because the winds were blowing the water away from the coast.  However, after the center moves north of an area, the wind will blow from the opposite direction and the water will rise quickly at the coast.  A station on the coast near Naples, Florida reported a water rise of six feet (two meters) in less than two hours after the center of Hurricane passed to the east.  Easterly winds on the eastern fringe of Hurricane Irma were blowing the water toward the coast and there were water rises from Miami, Florida to Charleston, South Carolina.  Strong southwesterly winds were still causing storm surges in the Florida Keys.  Hurricane Irma will also drop heavy rain over a prolonged period and it could cause freshwater flooding of rivers and streams.

Elsewhere over the tropical Atlantic Hurricane Jose moved away from the northern Leeward Islands on Sunday.  At 5:00 p.m. EDT om Sunday the center of Hurricane Jose was located at latitude 22.8°N and longitude 66.9°W which put it about 285 miles (455 km) east-northeast of Grand Turk Island.  Jose was moving toward northwest at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (225 km/h).  Hurricane Jose is forecast to stall over the tropical Atlantic east of the Bahamas and it could make a long slow loop during the next week.

Hurricane Irma Batters Florida Keys

Hurricane Irma battered the Florida Keys on Sunday morning.  At 9:00 a.m. EDT on Sunday morning the center of Hurricane Irma was located at latitude 24.5°N and longitude 81.5°W which put it about 30 miles (50 km) east-northeast of Key West, Florida.  Irma was moving toward the north-northwest at 8 m.p.h.  The maximum sustained wind speed was 130 m.p.h. (215 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  Hurricane Irma was a Category 4 hurricane on the Saffir-Simpson Scale.  The minimum surface pressure was 929 mb.

A Hurricane Warning was in effect for the portion of the coast from Fernandina Beach to Indian Pass, Florida including the Florida Keys and Lake Okeechobee.   A Hurricane Watch was in effect for the portion of the coast from Fernandina Beach, Florida to Edisto Beach, South Carolina.  A Tropical Storm Warning is in effect for the portion of the coast from Fernandina Beach to South Santee River, South Carolina and from Indian Pass to the Okaloosa/Walton County line.

A Hurricane Warning is in effect for the Cuban provinces of La Habana and Matanzas.  A Tropical Storm Watch is in effect for Bimini and Grand Bahama Island.

An outer eyewall started to wrap around the original eye of Hurricane Irma, but Irma did not go through an eyewall repacement cycle.  The original eyewall remained intact and the strongest winds were occurring in that eyewall.  The uncompleted formation of an outer eyewall did result in an increase in the size of Hurricane Irma.  Winds to hurricane force extend out about 80 miles (130 km) from the center of circulation.  Winds to tropical storm force extend out over 200 miles (320 km) from the center.

The Hurricane Intensity Index (HII) for Hurricane Irma was 25.1.  The Hurricane Size Index (HSI) was 24.2 and the Hurricane Wind Intensity Size Index (HWISI) was 49.3.  Hurricane Irma is not quite as strong as Hurricane Charley was when Charley hit southwest Florida.  However, Hurricane Irma is much bigger than Charley was.  Hurricane Irma is stronger than Hurricane Wilma was when Wilma hit south Florida in 2005.  Irma is a little smaller than Wilma was.

Carysfort Reef Light near Key Largo reported a wind gust of 93 m.p.h. (150 km/h).  Hurricane Irma is causing winds to hurricane force over much of the Florida Keys.  Winds to tropical storm force are occurring in areas around Miami, Florida.

Hurricane Irma has turned toward the north.  The core of Hurricane Irma could make a landfall on the southwest coast of Florida between Everglades City and Naples, Florida later this afternoon.  Hurricane Irma could move northward near the west coast of Florida.  The center of Hurricane Irma could reach the Tampa/St. Petersburg area and Central Florida on Sunday night.

Hurricane Irma is large and dangerous hurricane.  It is capable of causing widespread extensive damage.  There are likely to be widespread power outages.  Irma will also generate a storm surge of 15 feet (5 meters) in some locations.  Irma will drop locally heavy rain and flooding could occur in some places.

Hurricane Irma Grinds Along Cuba’s North Coast

Hurricane Irma ground its way along the northern coast of Cuba on Saturday morning.  At 2:00 p.m. EDT on Saturday the center of Hurricane Irma was located at latitude 23.1°N and longitude 80.2°W which put it about 145 miles (235 km) southeast of Key West, Florida.  Irma was moving toward the west at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 125 m.p.h. (205 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 941 mb.

A Hurricane Warning is in effect for the portion of the coast from Aucilla River to Fernandina Beach, Florida including the Florida Keys and Lake Okeechobee.  Hurricane Watches are in effect for the portions of the coast from Auculla River to Indian Pass, Florida and from Fernandina Beach, Florida to Edisto Beach, South Carolina.  Tropical Storm Watches are in effect for the portions of the coast from Indian Pass to the Okaloosa/Walton County line and from Edisto Beach to South Santee River, South Carolina.

A Hurricane Warning is in effect for the Cuban provinces of Camaguey, Ciego de Avila, Sancti Spiritus, Villa Clara, Matanzas, La Habana.  A Hurricane Warning was in effect for Andros Island, Bimini and Grand Bahama Island.  A Hurricane Watch and a Tropical Storm Warning was in effect for the Cuban provinces of Holguin and Las Tunas.

Hurricane Irma weakened on Saturday morning as the center moved along the northern coast of Cuba.  However, the core of Hurricane Irma remained intact.  There was an eye at the center of circulation.  A ring of strong thunderstorms surrounded the eye.  Numerous spiral bands were revolving around the core of Hurricane Irma.  Thunderstorms in the core of Irma were generating upper level divergence which was pumping mass away from the center of the hurricane.

Hurricane Irma is a large hurricane.  Winds to hurricane force extend out about 70 miles (110 km) from the center of circulation.  Winds to tropical storm force extend out about 185 miles (295 km) from the center.  The Hurricane Intensity Index (HII) for Irma was 23.6.  The Hurricane Size Index (HSI) was 23.6 and the Hurricane Wind Intensity Size Index (HWISI) was 47.2.  Those indices indicate Hurricane Irma is capable of causing widespread major damage.

Hurricane Irma will move through an environment favorable for intensification for another 12 to 18 hours.  Irma will over water where the Sea Surface Temperature is near 31°C.  The upper level winds are relatively weak and there will be little vertical wind shear.  Hurricane Irma is likely to intensify back to Category 4 on the Saffir-Simpson Scale and it could reach Category 5.  Hurricane Irma will move closer to an upper level trough over the eastern U.S. on Sunday.  Southerly winds on the eastern side of the trough will increase the vertical wind shear and Hurricane Irma will start to weaken.

Hurricane Irma is moving around the western end of a subtropical high pressure system over the Atlantic Ocean.  The subtropical high is steering Hurricane Irma toward the west-northwest.  Hurricane Irma will turn more toward the north-northwest when it reaches the western end of the high.  On its anticipated track the core of Hurricane Irma will move away from Cuba.  The center of Hurricane Irma will be near the Florida Keys by early Sunday morning.  Hurricane Irma could be near the southwest coast of Florida by Sunday afternoon.

Hurricane Irma will be capable of causing widespread extensive damage.  Winds blowing water toward the coast will generate significant storms surges.  Hurricane force winds will cause widespread damage as the Hurricane Irma moves near the west coast of Florida.

Elsewhere over the Atlantic Ocean Hurricane Jose was moving near the northern Leeward Islands.  At 2:00 p.m. EDT the center of Hurricane Jose was located at latitude 18.8°N and longitude 61.9°W which put it about 95 miles (155 km) east-northeast of the northern Leeward Islands.  Jose was moving toward the northwest at 14 m.p.h. (23 km/h).  The maximum sustained wind speed was 145 m.p.h. (230 km/h) and there were wind gusts to 175 m.p.h. (285 km/h).  The minimum surface pressure was 945 mb.

A Tropical Storm Warning was in effect for Barbuda, Anguilla, Sint Maarten, St. Martin and St. Barthelemy.

The core of Hurricane Jose and the strongest winds will move northeast of the northern Leeward Islands.  The southern part of the circulation will bring gusty winds which will hamper recovery efforts after Hurricane Irma.  Jose is forecast to stall over the Atlantic and there is much uncertainty about the ultimate long term track.

The remnants of Hurricane Katia were raining themselves out over eastern Mexico.  At 11:00 a.m. EDT on Saturday the center of Tropical Depression Katia was located at latitude 20.0°N and longitude 97.9°W which put it about 125 miles (200 km) west-northwest of Veracruz, Mexico.  Katia was moving toward the west-southwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 35 m.p.h (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1004 mb.
