Major Hurricane Dorian Moves Toward the Carolinas

Major Hurricane Dorian moved toward the Carolinas on Wednesday night.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Dorian was located at latitude 31.3°N and longitude 79.6°W which put it about 105 miles (170 km) south of Charleston, South Carolina.  Dorian was moving toward the north at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 115 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (220 km/h).  The minimum surface pressure was 955 mb.

A Hurricane Warning was in effect for the portion of the coast from Savannah River, Georgia to the North Carolina/Virginia border including Albemarle and Pamlico Sounds.  A Hurricane Watch was in effect for the portion of the coast from the mouth of the St. Mary’s River, Florida to Savannah River, Georgia.  Tropical Storm Warnings were in effect for the portions of the coast from the mouth of the St. Mary’s River to Savannah River, Georgia and from the North Carolina/Virginia border to Chincoteague, Virginia.  A Tropical Storm Warning was also in effect for Chesapeak Bay south of Smith Point.  Tropical Storm Watches were in effect for the portion of the coast from Chincoteague, Virginia to Fenwick Island, Delaware, for Chesapeake Bay from Smith Point to Drum Point and for the Tidal Potomac south of Cobb Island.

Hurricane Dorian strengthened back into a major hurricane on Wednesday night as it moved over the warm water in the Gulf Stream.  A large eye with a diameter of 45 miles (75 km) became more circular and symmetrical.  The ring of thunderstorms surrounding the eye became continuous and a little thicker.  The strongest winds were occurring in that ring of storms.  Other bands of showers and thunderstorms revolving around the core of Hurricane Dorian also got stronger.  Storms around the core of Dorian generated upper level divergence which pumped mass away from the hurricane and the surface pressure decreased.

The circulation around Hurricane Dorian increased in size on Wednesday.  Winds to hurricane force extended out about 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out about 200 miles (320 km) from the center.  The Hurricane Intensity Index (HII) for Hurricane Dorian was 20.6.  The Hurricane Size Index (HSI) was 22.6 and the Hurricane Wind Intensity Size Index (HWISI) was 43.2.  Hurricane Dorian was capable of causing widespread major damage.

Hurricane Dorian will move through an environment favorable for intensification during the next 12 hours.  Dorian will move over water where the Sea Surface Temperature is near 28°C.  It will move through a region where the upper level winds are weak and there is little vertical wind shear.  Hurricane Dorian could get a little stronger during the night.  An upper level trough over the central U.S. will move toward Hurricane Dorian on Thursday.  The upper level trough will produce southwesterly winds which will blow toward the top of the hurricane.  Those winds will cause the vertical wind shear to increase, which will cause Dorian to start to weaken.

Hurricane Dorian will move around the western end of a subtropical ridge over the western Atlantic Ocean.  The ridge will steer Dorian toward the north on Wednesday night.  The upper level trough will turn Hurricane Dorian toward the northeast on Thursday.  On its anticipated track Hurricane Dorian could approach the coast of South Carolina on Thursday morning.  Dorian will move along the coast of North Carolina on Thursday afternoon and Thursday night.

Even if the center of Hurricane Dorian stays just south of the coast of South Carolina and North Carolina, the large circulation means that locations near the coast are likely to get hurricane force winds.  Winds blowing water toward the coast could cause storm surges of 5 to 8 feet (1.5 to 2.5 meters) in some locations.  Dorian could also drop locally heavy rain and cause flash flooding  near the coast.

Elsewhere, Tropical Storm Fernand made landfall north of La Pesca, Mexico on Wednesday and Tropical Storm Gabrielle developed south of the Azores.  Ar 11:00 p.m. EDT on Wednesday the center of Tropical Depression Fernand was located at latitude 25.0°N and longitude 99.0°W which put it about 100 miles (160 km) west-northwest of La Pesca, Mexico.  Dorian was moving toward the west-northwest at 9 m.p.h. (15 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 1007 mb.

At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Gabrielle was located at latitude 21.5°N and longitude 34.4°W which put it about 1220 miles (1965 km) south-southwest of the Azores.  Gabrielle was moving toward the northwest at 7 m.p.h. (11 km/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 m/h).  The minimum surface pressure was 1002 mb.

Tropical Storm Fernand Forms Over W. Gulf of Mexico, Dorian Edges Away From Bahamas

Tropical Storm Fernand formed over the western Gulf of Mexico and powerful Hurricane Dorian edged slowly away from the Northwestern Bahamas on Tuesday afternoon.  At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Fernand was located at latitude 23.5°N and longitude 95.3°W which put it about 160 miles (260 km) east of La Pesca, Mexico.  Fernand was moving toward the west at 7 m.p.h. (11 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 1004 mb.

The government of Mexico issued a Tropical Storm Warning that was in effect for the portion of the coast from Barra del Tordo to the mouth of the Rio Grande River.

The circulation around an area of low pressure over the western Gulf of Mexico exhibited greater organization on Tuesday afternoon and the National Hurricane Center designated the system as Tropical Storm Fernand.  The circulation around Fernand consisted of a broad area of lower pressure.  One rainband wrapped around the northern periphery of the circulation and a second rainband wrapped around the western periphery of the circulation.  Bands in other parts of the circulation consisted primarily of showers and low clouds.  Winds to tropical storm force extended out about 105 miles (170 km) from the center of the circulation on the western side of Fernand.

Tropical Storm Fernand will move through an environment favorable for intensification during the next 24 hours.  Fernand will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Fernand is likely to strengthen during the next 24 hours.  However, the broad circulation will limit how fast the tropical storm can intensify.

Tropical Storm Fernand will move south of an ridge of high pressure over the southern U.S.  The ridge will Fernand toward the west-northwest during the next day or two.  On its anticipated track Tropical Storm Fernand is expected to make landfall on the coast of Mexico between La Pesca and Mezquital on Wednesday.  Fernand will bring gusty winds and locally heavy rain.  The rain could cause flash floods where Tropical Storm Fernand moves inland over northeastern Mexico.  Fernand could also cause a storm surge of 6 feet (2 meters) along the coast.

Elsewhere over the Atlantic Ocean, powerful Hurricane Dorian began to edge slowly away from the Northwestern Bahamas.  At 2:00 p.m. EDT on Tuesday the center of Hurricane Dorian was located at latitude 27.5°N and longitude 78.7°W which put it about 105 miles (170 km) east of Ft. Pierce, Florida.  Dorian was moving toward the northwest at 5 m.p.h. (8 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. (215 km/h).  The minimum surface pressure was 959 mb.

Hurricane Warnings were in effect for the portions of the coast from Jupiter Inlet to Ponte Vedra Beach, Florida and from Edisto Beach to South Santee River, South Carolina.  Hurricane Watches were in effect for the portions of the coast from Ponte Vedra Beach to Edisto Beach and from South Santee River to Duck, North Carolina including Albemarle and Pamlico Sounds.  Tropical Storm Warnings were in effect for the portions of the coast from Deerfield Beach to Jupiter Inlet, Florida and from Ponte Vedra Beach to Edisto Beach.  The Hurricane Warnings for the Northwestern Bahamas including the Abacos and Grand Bahama Island had been changed to Tropical Storm Warnings, since Dorian was moving away from those locations.

Hurricane Dorian finally started to move around the western end of a subtropical high pressure system over the Atlantic Ocean on Tuesday.  An upper level trough over the U.S. will turn Dorian toward the northeast on Wednesday.  On its anticipated track the center of Hurricane Dorian will stay offshore and move parallel to east coast of Florida.  A small deviation to the west could bring the core of Dorian close to the coast.  The center of Hurricane Dorian could move very close to the coast of South Carolina and North Carolina on Thursday.  The circulation around Hurricane Dorian increased in size on Tuesday.  Winds to hurricane force extended out about 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out about 170 miles (275 km) from the center.

Juliette Rapidly Intensifies Into a Major Hurricane

Hurricane Juliette rapidly intensified into a major hurricane southwest of Baja California on Monday. At 11:00 p.m. EDT on Monday the center of Hurricane Juliette was located at latitude 17.8°N and longitude 114.0°W which put it abou 440 miles (710 km) southwest of the southern tip of Baja California.  Juliette was moving toward the northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 140 m.p.h. (220 km/h).  The minimum surface pressure was 963 mb.

Hurricane Juliette intensified rapidly on Monday as it moved through an environment of warm water and littler vertical wind shear.  An eye developed at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of strong thunderstorms increased in the eastern half of the circulation.  Bands in the western half of the circulation contained fewer thunderstorms.  Storms around the core of Juliette generated strong upper level divergence which pumped mass away from the hurricane.  Winds to hurricane force extended out about 20 miles (30 km) from the center of circulation.  Winds to tropical storm force extended out about 125 miles (200 km) from the center.

Hurricane Juliette will remain in an environment favorable for intensification for another day or so.  Juliette will move over water where the Sea Surface Temperature is near 28°C.  It will move through a region where the upper level winds are not too strong and there will be little vertical wind shear.  Hurricane Juliette could strengthen further on Tuesday.  Juliette will move over cooler water later this week and it will start to weaken.

Hurricane Juliette will move southwest of a ridge over the southwestern U.S.  The ridge will steer Juliette toward the northwest.  On its anticipated track Hurricane Juliette will remain well west of Baja California.

Tropical Storm Juliette Develops Rapidly South of Baja California

Tropical Storm Juliette developed rapidly south of Baja California on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Juliette was located at latitude 14.3°N and longitude 108.8°W which put it about 600 miles (965 km) south of the southern tip of Baja California.  Juliette was moving toward the northwest at 14 m.p.h. (22 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 1000 mb.

The circulation around Tropical Storm Juliette organized very rapidly on Sunday.  The inner end of a rainband wrapped around the center of circulation and a circular eye appeared to be forming at the center of Juliette.  Other bands of showers and thunderstorms were revolving around the core of the circulation.  Storms near the core were generating upper level divergence which was pumping mass away from the tropical storm.  Winds to tropical storm force extended out about 80 miles (130 km) from the center of circulation.

Tropical Storm Juliette will move through an environment very favorable for intensification.  Juliette will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will is little vertical wind shear.  Tropical Storm Juliette is likely to continue to intensify rapidly during the next day or two.  Juliette is likely to strengthen into a hurricane within 12 hours and it could be a major hurricane within 48 hours.

Tropical Storm Ivo Forms South of Baja California

Tropical Storm Ivo formed south of Baja California on Wednesday.  At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Ivo was located at latitude 15.8°N and longitude 109.5°W which put it about 490 miles (790 km) south of the southern tip of Baja California.  Ivo was moving toward the west-northwest at 20 m.p.h. (32 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 1004 mb.

A distinct low level center of circulation developed in a low pressure system south of Baja California on Wednesday and the National Hurricane Center designated the system as Tropical Storm Ivo.  A band of thunderstorms wrapped around the western and southern parts of the center of circulation and satellite sensors indicated that winds to tropical storm force were occurring in the band.  Other bands of thunderstorms developed in the western half of Tropical Storm Ivo.  Bands in the eastern half of the circulation consisted primarily of showers and lower clouds.  Thunderstorms near the center of Ivo began to generate upper level divergence which was pumping mass away from the tropical storm.

Tropical Storm Ivo will move through an environment favorable for intensification during the next 36 to 48 hours.  Ivo will move over water where the Sea Surface Temperature is near 29°C.  It will move south of an upper level ridge that stretches from west of California to northern Mexico.  The ridge will produce easterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear, which could slow the rate at which Tropical Storm Ivo intensifies. However, the shear will not be strong enough to prevent intensification and Ivo could strengthen into a hurricane within 36 hours.  Tropical Storm Ivo will start to move over cooler water when it moves west of Baja California and that will cause it to weaken during the weekend.

The ridge will steer Tropical Storm Ivo toward the northwest during the next several days.  On its anticipated track Tropical Storm Ivo will move west of Baja California.  The primary impact of Ivo will be to generate waves which will reach the west coast of Baja California and southern California.

Tropical Storm Henriette Forms Southwest of Baja California

Tropical Storm Henriette formed southwest of Baja California on Monday.  At 11:00 a.m. EDT on Monday the center of Tropical Storm Henriette was located at latitude 19.7°N and longitude 112.2°W which put it about 265 miles (430 km) southwest of the southern tip of Baja California.  Henriette was moving toward the west-northwest at 12 m.p.h. (19 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 1005 mb.

The distribution of thunderstorms around Tropical Storm Henriette was highly asymmetrical.  Most of the thunderstorms were occurring southwest of the center of circulation.  Bands in other parts of the circulation consisted primarily of showers and lower clouds.  Tropical Storm Henriette was south of a narrow upper level ridge.  The ridge was producing northeasterly winds which were blowing across the top of Henriette.  Those winds were causing strong vertical wind shear and they were the cause of the asymmetrical distribution of thunderstorms.

Tropical Storm Henriette will be moving through a region that will be mostly unfavorable for intensification.  Henriette will move over water where the Sea Surface Temperature is near 28.5°C.  So, there will be sufficient energy in the upper ocean to support intensification.  However, the upper level ridge will continue to cause strong vertical wind shear which will prevent intensification.  Tropical Storm Henriette is likely to weaken in a day or two when it moves over colder water.

Tropical Storm Henriette will move south of a subtropical ridge over the Eastern North Pacific Ocean.  The ridge will steer Henriette toward the west-northwest during the next several days.  On its anticipated track Tropical Storm Henriette will move farther away from Baja California.

Tropical Storm Gil Forms Over Eastern North Pacific

Tropical Storm Gil formed over the Eastern North Pacific Ocean on Saturday.  A scatterometer onboard a satellite found winds to tropical storm force northeast of the center of former Tropical Depression Eight-E and the National Hurricane Center designated the system as Tropical Storm Gil.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Gil was located at latitude 15.0°N and longitude 122.4°W which put it about 980 miles (1580 km) west-southwest of the southern tip of Baja California.  Gil was moving toward the west-northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to about 50 m.p.h. (80 km/h).  The minimum surface pressure was 1006 mb.

The circulation around Tropical Storm Gil was asymmetrical.  There was a distinct low level center of circulation which was visible on satellite imagery.  However, the stronger thunderstorms were occurring east of the center of circulation.  Bands in the western half of Gil consisted primarily of showers and lower clouds.  An upper level trough south of California was producing strong westerly winds which were blowing across the top of the circulation.  The winds were causing strong vertical wind shear and they were contributing to the asymmetrical distribution of thunderstorms.  Tropical storm force winds were occurring within 80 miles (130 km) of the center of Tropical Storm Gil only in the northeastern quadrant of of the circulation.

Tropical Storm Gil will move through an environment only marginally favorable for intensification.  Gil will move over water where the Sea Surface Temperature is near 27°C.  However, the upper level trough will continue to cause significant vertical wind shear.  The strong vertical wind shear will inhibit intensification of Tropical Storm Gil.  Gil could weaken to a tropical depression if the shear increases.

Tropical Storm Gil will move south of a subtropical ridge over the Eastern North Pacific Ocean.  The ridge will steer Gil in a westward direction during the next several days.  On its anticipated track, Tropical Storm Gil will move farther away from Mexico.

Elsewhere over the Central Pacific Ocean, strong vertical wind shear was weakening Tropical Storm Erick and Tropical Storm Flossie.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Erick was located at latitude 17.3°N and longitude 163.9°W which put it about 480 miles (770 km) southwest of Honolulu, Hawaii.  Erick was moving toward the west at 13 m.p.h. (20 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 1005 mb.

At 5:00 p.m. EDT on Saturday the center of Tropical Storm Flossie was located at latitude 18.8°N and longitude 144.5°W which put it about 695 miles (1115 km) east of Hilo, Hawaii.  Flossie was moving toward the west-northwest at 13 m.p.h. (20 km/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 1003 mb.

Erick Rapidly Intensifies Into Major Hurricane

Erick rapidly intensified into a major hurricane over the the Central Pacific Ocean during Monday night.  At 11:00 a.m. EDT on Tuesday the center of Hurricane Erick was located at latitude 13.4°N and longitude 142.8°W which put it about 920 miles (1485 km) east-southeast of Hilo, Hawaii.  Erick was moving toward the west at 17 m.p.h. (28 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 140 m.p.h. (225 km/h).  The minimum surface pressure was 966 mb.

The core of Hurricane Erick intensified rapidly during the overnight hours.  The eye became more circular and distinct on infrared satellite images.  The diameter of the eye was about 12 miles (19 km) on Tuesday morning.  Thunderstorms in the ring around the eye grew taller and the wind speed around the eye increased quickly.  Storms around the core of Erick generated strong upper level divergence which pumped mass away from the hurricane.  Multiple bands of showers and thunderstorms were revolving around the core of the circulation.

The circulation around Hurricane Erick was relatively small.  Winds to hurricane force were occurring within 25 miles (40 km) of the center of circulation.  Winds to tropical storm force extended out about 100 miles (160 km) of the center.  The Hurricane Intensity Index (HII) for Hurricane Erick was 20.6.  The Hurricane Size Index (HSI) was 8.2 and the Hurricane Wind Intensity Size Index (HWISI) was 28.8.

Hurricane Erick will remain in an environment favorable for intensification for about another 24 hours.  Erick will move over water where the Sea Surface Temperature is near 28°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear during the next day or so.  Hurricane Erick will approach an upper level trough east of Hawaii on Wednesday.  The trough will produce stronger southwesterly winds which will cause the vertical wind shear to increase.  Hurricane Erick will start to weaken when the wind shear increases.

Hurricane Erick will move south of a subtropical high pressure system over the Eastern and Central North Pacific Ocean.  The high will steer Erick toward the west during the next several days.  On its anticipated track Hurricane Erick could be south of Hawaii on Thursday night.

Elsewhere, Tropical Storm Flossie was nearing hurricane strength over the Eastern North Pacific Ocean.  At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Flossie was located at latitude 12.2°N and longitude 120.5°W which put it about 1015 mile (1635 km) southwest of the southern tip of Baja California.  Flossie was moving toward the west at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 999 mb.

Hurricane Erik and Tropical Storm Flossie Strengthen

Hurricane Erick and Tropical Storm Flossie both moved westward and strengthened over the Eastern North Pacific Ocean on Monday.  At 11:00 p.m. EDT on Monday the center of Hurricane Erick was located at latitude 12.7°N and longitude 140.0°W which put it about 1110 miles (1790 km) east-southeast of Hilo, Hawaii.  Erick was moving west at 18 m.p.h. (30 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 990 mb.

The circulation around Hurricane Erick exhibited greater organization on Monday.  A small eye developed at the center of circulation.  The eye was surround by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms,  Winds to hurricane force extended out about 20 miles (30 km) from the center of circulation.  Bands of showers and thunderstorms were revolving around the core of Hurricane Erick.  Storms near the core were generating upper level divergence which was pumping mass away from the hurricane.  Winds to tropical storm force extended out about 70 miles (110 km) from the center.

Hurricane Erick will move through an environment favorable for intensification during the next 48 hours.  Erick will move over water where the Sea Surface Temperature is near 28°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Erick will intensify during the next two days and it could strengthen into a major hurricane.  Eventually, Erick will approach an upper level trough east of Hawaii and the vertical wind shear will increase.

Hurricane Erick will move south of a subtropical high pressure system over the Eastern North Pacific Ocean.  The high will steer Erick toward the west. On its anticipated track Hurricane Erick could be southeast of Hawaii on Thursday.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Flossie was also intensifying.  At 11:00 p.m. EDT on Monday the center of Tropical Storm Flossie was located at latitude 12.3°N and longitude 117.8°W which put it about 895 miles (1445 km) southwest of the southern tip of Baja California.  Flossie was moving toward the west at 17 m.p.h. (28 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 1001 mb.  Tropical Storm Flossie is also forecast to move westward and strengthen.

Tropical Storm Dalila Develops Southwest of Baja California

Tropical Storm Dalila developed southwest of Baja California on Tuesday morning.  More thunderstorms formed to the south of the center of former Tropical Depression Five-E and the circulation produced wind speeds to tropical storm force.  At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Dalila was located at latitude 18.7°N and longitude 117.7°W which put it about 580 miles (935 km) west-southwest of the southern tip of Baja California.  Dalila was moving toward the north-northwest at 8 m.p.h. (13 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 1006 mb.

Although Tropical Storm Dalila did have a definite low level center of circulation, the center was relatively broad.  In addition, most of the stronger thunderstorms were occurring south of the center of circulation.  Bands in other parts of the tropical storm consisted primarily of showers and lower clouds.  Dalila was moving southwest of a large upper level high pressure system over the western U.S. and Mexico.  Clockwise flow around the high was producing northeasterly winds which were blowing toward the top of Tropical Storm Dalila.  Those winds were causing moderate vertical wind shear and they were a major reason for the asymmetrical distribution of thunderstorms in the southern part of the tropical storm.

Tropical Storm Dalila will move into an environment that will become increasingly unfavorable for intensification.  The upper level high will continue to produce wind shear which will inhibit strengthening.  Dalila is currently over water where the Sea Surface Temperature is near 26°C, but it will move over colder water during the next several days.  Dalila could maintain tropical storm intensity for another 12 to 24 hours, but it is likely to weaken during the next several days.

Tropical Storm Dalila will continue to move around the southwestern part of the upper level high over the western U.S. and Mexico.  The high will steer Dalila toward the northwest during the next 12 to 24 hours.  When the remaining stronger thunderstorms weaken, Tropical Storm Dalila will be steered by winds at lower levels in the atmosphere and those winds should steer it more toward the west.  On its anticipated track Tropical Storm Dalila will weaken while it moves farther over the Eastern North Pacific Ocean.
