Florence Strengthens Back Into a Hurricane

Florence strengthened back into a hurricane on Sunday morning.  At 11:00 a.m. EDT on Sunday the center of Hurricane Florence was located at latitude 24.4°N and longitude 56.3°W which put it about 750 miles (1210 km) southeast of Bermuda.  Florence was moving toward the west at 6 m.p.h. (10 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 984 mb.

Hurricane Florence was better organized on Sunday morning.  A NOAA research aircraft reported a circular eye with a diameter of 24 miles (39 km).  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Hurricane Florence.  Storms near the core were generating upper level divergence which was pumping mass away from the hurricane.  Winds to hurricane force extended out about 20 miles (35 km) to the east of the center of circulation.  Winds to tropical storm force extended out about 115 miles (185 km) to the north of the center and about 50 miles (80 km) to the south of the center.

Hurricane Florence will be moving through an environment favorable for intensification.  Florence 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 be little vertical wind shear.  Hurricane Florence will strengthen and it could intensify rapidly at times.  Florence is likely to be a major hurricane on Monday.

Hurricane Florence will move around the western end of a subtropical high pressure system over the western Atlantic Ocean.  The high will steer Florence in a general west-northwesterly direction.  On its anticipated track the center of Hurricane Florence will approach the southeast coast of the U.S. on Thursday.  It is likely to be a major hurricane at that time.

Elsewhere, Tropical Storm Helene and Tropical Storm Isaac moved westward over the tropical Atlantic Ocean.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Helene was located at latitude 13.2°N and longitude 25.0°W which put it about 120 miles (195 km) south-southwest of the Cabo Verde Islands.  Helene was moving toward the west at 13 m.p.h. (20 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 997 mb.  Tropical Storm Warnings were in effect for Santiago, Fogo and Brava.

At 11:00 a.m. EDT on Sunday the center of Tropical Storm Isaac was located at latitude 14.3°N and longitude 39.1°W which put it about 1470 miles (2370 km) east of the Windward Islands.  Isaac was moving toward the west at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 65 m.p.h. (105km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 999 mb.

Tropical Storm Florence Reorganizes Southeast of Bermuda

Tropical Storm Florence reorganized southeast of Bermuda on Saturday.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Florence was located at latitude 24.6°N and longitude 55.2°W which put it about 790 miles (1270 km) southeast of Bermuda.  Florence was moving toward the west at 6 m.p.h. (10 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 989 mb.

Vertical wind shear decreased around Tropical Storm Florence and the circulation showed evidence of better organization.  Stronger thunderstorms developed near the center of circulation and a primary rainband wrapped about three quarters of the way around the center.  An eye appeared to be forming.  Thunderstorms near the center generated more upper level divergence which pumped away mass and the surface pressure decreased on Saturday.  More thunderstorms also developed in other rainbands that were revolving around the core of the circulation.  Tropical Storm Florence appeared to be on the threshold of regaining hurricane intensity.

Tropical Storm Florence will be moving through an environment favorable for intensification during the next two or three days.  Florence will move over water where the Sea Surface Temperature is near 29°C.  It will move into a region where the upper level winds are weaker and there will be less vertical wind shear.  Tropical Storm Florence will intensify back into a hurricane on Sunday.  It could intensify rapidly once a eye and complete eyewall form.  Florence is likely to become a major hurricane by early next week.

Tropical Storm Florence will move near the western end of a subtropical high pressure system over the western Atlantic Ocean.  The high will steer Florence in a general west-northwesterly direction during the next few days.  On its anticipated track Florence could approach the southeast coast of the U.S. by Thursday.  It is likely to be a major hurricane at that time.  The steering currents could weaken when Florence approaches the U.S. and it is too early to make a precise forecast of landfall.

Elsewhere, Tropical Storms Helene and Isaac strengthened over the eastern tropical Atlantic Ocean.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Helene was located at latitude 13.2°N and longitude 22.8°W which put it about 155 miles (250 km) southeast of the Cabo Verde Islands.  Helene was moving toward the west at 13 m.p.h. (20 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. (120km/h).  The minimum surface pressure was 999 mb.  Tropical Storm Warnings were in effect for Santiago, Fogo and Brava.

At 11:00 p.m. EDT the center of Tropical Storm Isaac was located at latitude 14.4°N and longitude 37.5°W which put it about 1580 miles (2540 km) east of the Windward Islands.  Isaac was moving toward the west at 8 m.p.h. (13 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 1002 mb.

Florence Weakens to a Tropical Storm

Former Hurricane Florence weakened to a tropical storm on Thursday.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Florence was located at latitude 25.1°N and longitude 49.8°W which put it about 1035 miles (1665 km) east-southeast of Bermuda.  Florence was moving toward the west-northwest at 7 m.p.h. (11 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 993 mb.

An upper level trough west of former Hurricane Florence produced strong southwesterly winds which blew across the top of the circulation.  Those winds caused strong vertical wind shear and Florence weakened into a tropical storm.  Thunderstorms dissipated in rainbands in the western half of the tropical storm.  The ring of thunderstorms around the eye weakened and the western side of the eyewall was disrupted.  However, a distinct low level center of circulation persisted.  Thunderstorms northeast of the center still generated upper level divergence which pumped mass away to the northeast.

Tropical Storm Florence could weaken further on Friday because it will still be in the area of strong vertical wind shear.  However, as long as the lower part of the circulation remains intact, Tropical Storm Florence will be likely to strengthen during the weekend.  Florence is currently over water where the Sea Surface Temperature is near 28°C.  It will move over even warmer water during the weekend.  When Florence moves farther west, it will move into an area where the upper level winds are weaker and the wind shear will decrease.  Tropical Storm Florence is likely to intensify back into a hurricane during the weekend.

Tropical Storm Florence will move south of the subtropical high over the Atlantic Ocean.  The high will steer Florence in a generally west-northwesterly direction.  On its anticipated track, Florence could be southeast of Bermuda by Monday.  Florence could approach the east coast of the U.S. later next week.

Tropical Storm Chris Develops South of Cape Hatteras, Beryl Nears Lesser Antilles

Tropical Storm Chris developed south of Cape Hatteras on Sunday morning, while Tropical Storm Beryl neared the Lesser Antilles.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Chris was located at latitude 32.9°N and longitude 75.0°W which put it about 160 miles (260 km) south of Cape Hatteras, North Carolina.  Chris was nearly stationary.  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 1006 mb.

Thunderstorms developed closer to the center of circulation on Sunday morning and the National Hurricane Center designated former Tropical Depression Three as Tropical Storm Chris.  The circulation of Chris was organizing quickly.  A band of showers and thunderstorms was wrapping around the center of circulation.  Several other rainbands were revolving around the core of the tropical storm.  The bands northwest of the center were weaker because there was drier air in that part of Chris.  The storms near the center of circulation were beginning to generate upper level divergence.

Tropical Storm Chris will remain in an environment favorable for intensification for the next two or three days.  The water in the upper portion of the Atlantic Ocean east of the Carolinas is warmer than normal.  Tropical Storm Chris will be over water where the Sea Surface Temperature is near 28°C.  Chris will be southeast of an upper level trough over the northeastern quarter of the U.S. and it will be under a small upper level ridge.  The upper level winds will be weak and there will be little vertical wind shear.  Tropical Storm Chris will continue to intensify and it could strengthen to a hurricane in the next day or two.

Since Tropical Storm Chris is under the small upper level ridge, the steering winds are weak.  Chris may not move much during the next 24 to 48 hours.  Tropical Storm Chris is forecast to linger of the coast of the Carolinas for several days.  Eventually an upper level trough will approach from the west and start to push Chris toward the northeast.

Elsewhere, Tropical Storm Beryl was nearing the Lesser Antilles on Sunday morning.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Beryl was located at latitude 14.4°N and longitude 57.9°W which put it about 210 miles (335 km) east of Martinique.  Beryl was moving toward the west-northwest at 23 m.p.h. (37 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 1007 mb.

Tropical Storm Warnings were in effect for Dominica and Guadeloupe.  Tropical Storm Watches were in effect for Saba, St. Eustatius, St. Maarten, St. Martin, Martinique, St. Lucia, and St. Barthelemy.

Thunderstorms continued to develop near the center of Tropical Storm Beryl on Sunday morning and the weakening trend halted at least temporarily.  Beryl remained a small tropical storm.  Winds to tropical storm force only extended out about 45 miles (75 km) from the center of circulation.  There were several bands of showers and thunderstorms in the eastern half of Tropical Storm Beryl.  The bands in the western half of the circulation consisted primarily of showers and low clouds.

Tropical Storm Beryl is forecast to into a region where the easterly winds in the lower levels are stronger.  That would increase the vertical wind shear and make it difficult for the circulation to stay vertically coherent.  Beryl will move over water where the Sea Surface Temperature is near 27°C.  So, there will be enough energy in the upper ocean to support a tropical storm if the wind shear is not too strong.  Tropical Storm Beryl is forecast to weaken when it moves over the eastern Caribbean Sea, but that will depend on how strong the vertical shear gets.

Tropical Storm Beryl is moving south of the subtropical high over the Atlantic Ocean which is steering Beryl toward the west-northwest.  A general motion toward the west-northwest is forecast to continue for several more days.  On its anticipated track Tropical Storm Beryl will bring gusty winds and locally heavy rain to St. Lucia, Martinique, Dominica and Guadeloupe during the next few hours,

Tropical Storm Beryl Weakens East of the Lesser Antilles

Tropical Storm Beryl weakened on Saturday as it move closer to the Lesser Antilles.  At 11:00 p.m. EDT on Saturday the center of circulation was located at latitude 13.1°N and longitude 54.3°W which put it about 495 miles (795 km) east-southeast of the Lesser Antilles.  Beryl was moving toward the west-northwest at 18 m.p.h. (30 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 1005 mb.

Tropical Storm Warnings were in effect for Dominica and Guadeloupe.  Tropical Storm Watches were in effect for Saba, St. Eustatius, St. Maarten, Martinique, St. Martin, St. Barthelemy, Barbados and St. Lucia.

Tropical Storm Beryl moved into a region where the easterly winds in the lower level were stronger and the increased vertical wind shear started to blow the lower part of the circulation to the west of the upper part of Beryl.  It also seemed to move into an area of drier air, which caused most of the stronger thunderstorms to weaken.  There was still a well organized circulation in the lower levels, but it weakened on Saturday.  More thunderstorms developed near the center of circulation and on the eastern side of Tropical Storm Beryl in recent hours.  If those storms persist then Beryl could strengthen again, but if they dissipate quickly, then the tropical storm could weaken again on Sunday.

Tropical Storm Beryl will move through an environment that contains factors that are favorable for intensification and other factors that are unfavorable.  Beryl will move over water where the Sea Surface Temperature is near 27°C.  It will move through an area where the lower level winds are stronger and so there will be more vertical wind shear.  There will be areas of moister air within a larger area of drier air.  If the recently developed thunderstorms persist on Sunday, then the Beryl could strengthen again.  However, if the storms dissipate in a few hours, then Tropical Storm Beryl could weaken further.  The small size of the circulation means that rapid changes in intensity can occur.

Tropical Storm Beryl was moving south of the subtropical high over the Atlantic Ocean.  The high was steering Beryl toward the west-northwest and that general motion is forecast to continue for the next several days.  On its anticipated track Tropical Storm Beryl could reach the Lesser Antilles on Sunday night.  There is a lot of uncertainty about how strong Beryl may be when it reaches those islands.

Elsewhere over the Atlantic Ocean Tropical Depression Three spun south of Cape Hatteras.  At 11:00 p.m. EDT on Saturday the center of Tropical Depression Three was located at latitude 32.9°N and longitude 75.1°W which put it about 160 miles (260 km) south of Cape Hatteras, North Carolina.  It was nearly stationary.  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 1014 mb.

Hurricane Beryl Prompts Watches for Lesser Antilles, TD 3 Forms Southeast of Carolinas

The potential approach of Hurricane Beryl prompted the issuance of Watches for some of the Lesser Antilles on Friday afternoon, while at the same time Tropical Depression Three formed southeast of the Carolinas.  At 5:00 p.m. EDT on Friday the center of Hurricane Beryl was located at latitude 10.6°N and longitude 47.8°W which put it about 965 miles (1555 km) east-southeast of the Leeward Islands.  Beryl was moving toward the west at 15 m.p.h. (24 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 994 mb.

A Hurricane Watch has been issued for Dominica.  Tropical Storm Watches have been issued for Martinique, Guadeloupe, St. Martin and St. Barthelemy.

The circulation of Hurricane Beryl remains very small.  The pinhole is no longer visible on satellite imagery, although strong thunderstorms continue to develop near the center of circulation.  Short narrow bands or showers and thunderstorms are revolving around the core of Hurricane Beryl.  Winds to hurricane force only extend out about 10 miles (15 km) from the center of circulation.  Winds to tropical storm force extend out about 40 miles (65 km) from the center.

Hurricane Beryl will move through an environment favorable for intensification during the next 24 hours.  Beryl will move over water where the Sea Surface Temperature is near 27°C.  It is moving south of an upper level ridge.  The ridge is producing easterly winds which are blowing toward the top of the circulation.  However, the wind speeds are similar at all levels and there is currently little vertical wind shear.  Tropical Storm Beryl could intensify on Saturday, but the circulation is so small that any increase in wind shear could cause rapid weakening.

The subtropical ridge over the Atlantic Ocean is north of Hurricane Beryl and the ridge has been steering Beryl toward the west.  A motion more toward the west-northwest is forecast during the weekend.  On its anticipated track Hurricane Beryl will approach the Lesser Antilles later on Sunday.  That is the reason why the Watches were issued for some of those islands.  Beryl could still be a hurricane when it gets to the Lesser Antilles, but there is a lot of uncertainty about the intensity forecast because the hurricane is so small.

Elsewhere over the Atlantic Ocean, the National Hurricane Center designated an area of low pressure southeast of the coast of the Carolinas as Tropical Depression Three.  At 5:00 p.m. EDT on Friday the center of Tropical Depression Three was located at latitude 32.2°N and longitude 73.8°W which put it about 230 miles (370 km) south-southeast of Cape Hatteras, North Carolina.  It was moving toward the north-northwest at 5 m.p.h. (8 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 1016 mb.  Tropical Depression Three is forecast to meander off the coast of the Carolinas during the weekend.  It could strengthen into a tropical storm and there is a chance it could intensify into a hurricane next week.

Unusual Tropical Depression Alberto Reaches Michigan

Unusual Tropical Depression Alberto reached southern Michigan on Wednesday as it continued its northward journey from the Gulf of Mexico.  At 11:00 p.m. EDT on Wednesday the center of Tropical Depression Alberto was located at latitude 42.4°N and longitude 85.3°W which put it about 45 miles southwest of Lansing, Michigan.  Alberto was moving toward the north-northeast at 26 m.p.h. (43 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 996 mb.

The circulation of Tropical Depression Alberto remained intact even though it had been over land for more than two days.  There was a distinct low level center of circulation.  Several bands of showers and thunderstorms were revolving around the center of circulation.  Storms in the core of the circulation were generating upper level divergence.  Tropical Depression Alberto looked like a tropical cyclone on both satellite and radar imagery.

Gusty winds in some of the bands of showers and thunderstorms caused damage to trees and power lines in Indiana and Ohio.  Most of the damage was minor.  The peripheral parts of the circulation of Tropical Depression Alberto interacted with other weather system to produce bands of heavier rain over parts of the southeastern U.S.  The heavy rain contributed to flooding in several states.

Tropical Depression Alberto will move northeast across the Great Lakes and into Canada on Thursday.  The broader circulation around Alberto will again interact with other weather systems to produce bands of heavier rain.  The potential flooding will exist in several states in the southeastern U.S. and Great Lakes region.

Tropical Depression Alberto Drops Heavy Rain Over Southeast U.S.

Tropical Depression Alberto dropped heavy rain over portions of the southeastern U.S. on Tuesday.  At 11:00 p.m. EDT on Monday the center of Tropical Depression Alberto was located at latitude 36.3°N and longitude 87.5°W which put it about 45 miles (75 km) west-northwest of Nashville, Tennessee.  Alberto was moving toward the north at 16 m.p.h. (26 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 999 mb.

The core of Tropical Depression Alberto moved northward across Alabama and into Tennessee on Tuesday.  The circulation remained well developed and there was a band of showers and thunderstorms that surrounded most of the center.  Upper air data from Nashville, Tennessee indicated that the system might have a warm core and the Weather Prediction Center called it a Tropical Depression in the 11:00 p.m. EDT advisory.  A large counterclockwise circulation extended all the way to eastern North Carolina.  Bands of showers and thunderstorms were rotating northward in the eastern half of the circulation.

Those bands of showers and thunderstorms were dropping heavy rain as they passed over some locations.  A weather station in Asheville , North Carolina received nearly two inches of rain on Tuesday.  Heavier rain likely fell over parts of the Appalachians where the wind forced the air to rise up the mountains.  There were reports of flooding in several locations and Flash Flood Warnings were in effect for a number of counties in western North Carolina.  The National Weather Service Forecast Office in Greenville-Spartanburg, South Carolina issued a Flash Flood Emergency for areas downstream of the Lake Tahoma Dam in central McDowell County, North Carolina due to imminent failure of the dam.  Flash Flood Watches remained in effect from Georgia to Virginia and westward to the Lower Ohio River Valley.

The core of Tropical Depression Alberto will move northward across Indiana on Wednesday.  Bands of showers and thunderstorms will continue to drop heavy rain in the eastern half of the circulation.  The greatest risk for flooding will be in locations where bands of heavier rain remain over those areas for several hours.  The ground is already very wet in parts of the eastern U.S.  Water levels in streams and rivers could rise quickly.  Saturated ground could also contribute to potential mudslides in steeper terrain.

Subtropical Storm Alberto Makes Landfall in Northwest Florida

Subtropical Storm Alberto made landfall in northwest Florida late on Monday afternoon.  According to the National Hurricane Center the center of Subtropical Storm Alberto officially made landfall near Laguna Beach, Florida.  At 5:00 p.m. the center of Subtropical Storm Alberto was located at latitude 30.3°N and longitude 85.9°W which put it about 15 miles (25 km) west-northwest of Panama City, Florida.  Alberto was moving toward the north at 9 m.p.h. (15 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 994 mb.  A Tropical Storm Warning was in effect for the portion of the coast from Aucilla, River, Florida to the border between Florida and Alabama.

Subtropical Storm Alberto weakened slowly as it approached the coast of northwest Florida.  Several factors contributed to the weakening of Alberto.  Drier air spiraled into the core of the circulation.  The drier air inhibited the development of taller thunderstorms in the eastern and southern quadrants of the circulation.  Most of the stronger storms developed north and west of the center of circulation.  Daytime heating of the land made the atmosphere more unstable and the instability contributed to the development of thunderstorms in rainbands in those parts of Alberto.  Subtropical Storm Alberto also mixed cooler water to the surface as it moved slowly toward the coast of Florida.  The Sea Surface Temperature near the coast was about 26°C before Subtropical Storm Alberto arrived.  However, the layer of warmer water was very thin.  The winds caused by Alberto mixed the water in the upper levels of the Gulf of Mexico.  The mixing brought cooler water to the surface and the Sea Surface Temperature cooled to near 24°C.  The cooler water meant there was less energy to support the circulation around Subtropical Storm Alberto.

The circulation of Subtropical Storm Alberto will weaken slowly as it moves inland.  Winds blowing water toward the coast will continue to produce a storm surge of 3 to 4 feet (1 to 1.3 meters) east of the center of circulation for another 12 to 24 hours.  A large surface high pressure system over the Atlantic Ocean will steer Subtropical Storm Alberto slowly toward the north during the next several days.  Locally heavy rain could produce flooding as Alberto moves northward.  Flood Watches have been issued for areas between the Gulf Coast and the Lower Ohio River Valley.  Flood Watches have also been issued for places as far east as the Carolinas and Virginia.  The risk of flooding is even greater for locations that already received heavy rain from previous weather systems.

Subtropical Storm Alberto Strengthens on Its Way to Northwest Florida

Subtropical Storm Alberto strengthened on Sunday as it moved closer to northwest Florida.  At 11:00 p.m. EDT on Sunday the center of Subtropical Storm Alberto was located at latitude 28.5°N and longitude 85.8°W which put it about 95 miles (155 km) south-southwest of Apalachicola, Florida.  Alberto was moving toward the northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and the were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 991 mb.  A Tropical Storm Warning was in effect for the portion of the coast from Suwannee River, Florida to the border between Alabama and Mississippi.

The circulation of Subtropical Storm Alberto became more organized on Sunday.  A band of showers and thunderstorms wrapped around the center of circulation.  A band of drier air wrapped around the circulation just outside the rainband.  The band of drier air kept the circulation from developing a completely tropical structure and the National Hurricane Center continued to classify Alberto as a subtropical storm.  Alberto moved closer to the center of an upper level low over the Gulf of Mexico.  The upper level winds were weaker near the center of the low and the vertical wind shear decreased.  An upper level ridge over the Florida peninsula enhanced upper level divergence to the east of Alberto and the surface pressure decreases on Sunday.

Subtropical Storm Alberto will move through an environment somewhat favorable for intensification on Monday.  Alberto will move over water where the Sea Surface Temperature is near 28°C.  The upper level low will continue to produce some vertical wind shear.  The band of drier air will limit the development of thunderstorms outside the primary rainband.  Some intensification is possible during the next 12 hours, but the wind shear and drier air should limit any strengthening.

The upper low and the ridge over Florida will steer Subtropical Storm Alberto slowly toward the northwest.  On its anticipated track the center of Subtropical Storm Alberto is expected to make landfall over northwest Florida on Monday.  Alberto will be capable of causing minor wind damage.  Wind blowing water toward the coast will produce a storm surge of up to 4 to 7 feet (1.3 to 2.3 meters).  Alberto will drop heavy rain over parts of the southeastern U.S. and flooding could occur in some locations.
