Subtropical Storm Patty Forms, Tropical Storm Warning Issued for Azores

Subtropical Storm Patty formed over the North Atlantic Ocean on Saturday morning and a Tropical Storm Warning was issued for the Azores. At 5:00 a.m. EDT on Saturday the center of Subtropical Storm Patty was located at latitude 39.9°N and longitude 34.4°W which put the center about 426 miles (675 km) west-northwest of the Azores.  Patty was moving toward the east-southeast 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 km/h).  The minimum surface pressure was 998 mb.

A Tropical Storm Warning is in effect for the Azores.

A low pressure system at the center of an old occluded extratratropical cyclone over the North Atlantic Ocean was designated as Subtropical Storm Patty by the U.S. National Hurricane Center on Saturday morning.  The circulation around Subtropical Storm Patty was symmetrical.  A clear area like an eye was at the center of Patty’s circulation.  The clear area was surrounded by a ring of showers and low topped thunderstorms.  Bands of showers and thunderstorms were revolving around the center of Subtropical Storm Patty.

The circulation around Subtropical Storm Patty was large, since Patty formed at the center of an old occluded extratropical cyclone.  Winds to tropical storm force extended out 205 miles (330 km) in the southern side of Patty’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) in the northern side of Subtropical Storm Patty.

Subtropical Storm Patty will move through an environment only marginally favorable for intensification during the next 24 hours.  Patty will move over water where the Sea Surface Temperatures are near 21°C.  It will move under the southern part of an upper level low that was part of the old occluded extratropical cyclone.  The upper level low will produce westerly winds that will blow toward the top of Patty’s circulation.  Those winds will cause moderate vertical wind shear and the wind shear will inhibit intensification.  Subtropical Storm Patty could intensify a little during the next 24 hours, but it is likely to start to weaken on Sunday.

The upper level trough will steer Subtropical Storm Patty toward the east-southeast during the next 24 hours.  On its anticipated track, Subtropical Storm Patty will reach the western Azores on Saturday night.  Patty will move across the Azores on Sunday.

Subtropical Storm Patty will bring strong winds and heavy rain to the Azores during Saturday night and Sunday.  Strong winds could cause localized damage and electricity outages.

Tropical Storm Oscar Meanders Over Eastern Cuba

Tropical Storm Oscar meandered over eastern Cuba on Monday.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Oscar was located at latitude 21.0°N and longitude 76.1°W which put the center about 80 miles (130 km) northwest of Guantanamo, Cuba.  Oscar was moving toward the north-northwest 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.

Tropical Storm Warnings are in effect for the North Coast of Cuban province of Holguin and the North Coast of Cuban province of Guantanamo to Punta Maisi.  Tropical Storm Warnings are in effect for the Southeastern Bahamas.  Tropical Storm Warnings are in effect for the South Coast of Cuban province of Guantanamo and the North Coast of Cuban province of Las Tunas.  Tropical Storm Warnings are in effect for the Central Bahamas.

Former Hurricane Oscar weakened steadily as it meandered over eastern Cuba on Monday.  Many of the thunderstorms in Oscar’s circulation dissipated.  Bands of showers and low clouds were revolving around the center of Tropical Storm Oscar.  The strongest winds were occurring in bands over water north of Cuba.  The winds on land were blowing at less than tropical storm force.

The distribution of winds speeds in Tropical Storm Oscar was asymmetrical.  Winds to tropical storm force extended out 90 miles (145 km) in the eastern side of Oscar’s circulation.  Those winds were occurring in the part of the circulation that was over water.  The winds in the western side of Tropical Storm Oscar were blowing at less than tropical storm force.  Much of the western part of Oscar’s circulation was over eastern Cuba.

Tropical Storm Oscar will move through an environment only marginally favorable for intensification during the next 24 hours.  Oscar will move over water where the Sea Surface Temperatures are near 29°C.  However, it will move under the eastern side of an upper level trough over Florida.  The upper level trough will produce southwesterly winds that will blow toward the top of Oscar’s circulation.  Those winds will cause strong vertical wind shear.  The wind shear will inhibit intensification, but Tropical Storm Oscar could get a little stronger on Tuesday.

The upper level trough over Florida will steer Tropical Storm Oscar toward the northeast during the next 24 hours.  On its anticipated track Oscar will move over the Central Bahamas on Tuesday.  Tropical Storm Oscar will bring gusty winds and locally heavy rain to the Central Bahamas.

Hurricane Oscar Brings Wind and Rain to Eastern Cuba

Hurricane Oscar brought wind and rain to eastern Cuba on Sunday night.  At 8:00 p.m. EDT on Sunday the center of Hurricane Oscar was located at latitude 20.2°N and longitude 74.5°W which put the center about 45 miles (75 km) east of Guantanamo, Cuba.  Oscar was moving toward the west-southwest 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 988 mb.

Hurricane Warnings are in effect for the North Coast of Cuban province of Holguin and the North Coast of Cuban province of Guantanamo to Punta Maisi.

A Tropical Storm Watch is in effect for the North Coast of Cuban province of Camaguey.  A Tropical Storm Watch is also in effect for the Central Bahamas.

The center of Hurricane Oscar made landfall on the coast of eastern Cuba east of Guantanamo on Sunday evening.  A very small eye with a diameter of 4 miles (6 km) was at the center of Oscar’s circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Short bands of showers and thunderstorms were revolving around the center of Hurricane Oscar.

The circulation around Hurricane Oscar was very small.  Winds to hurricane force extended out 15 miles (25 km) on the northern side of Oscar’s circulation.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Hurricane Oscar.

Hurricane Oscar will move around the southern side of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Oscar toward the west during the next 24 hours.  On its anticipated track, Hurricane Oscar will move across eastern Cuba on Sunday night and on Monday.

Hurricane Oscar will weaken to a tropical storm as it moves inland over eastern Cuba.  Even though Oscar will weaken, it will still bring strong winds and heavy rain to eastern Cuba.  Heavy rain is likely to cause flash floods in some locations.

Hurricane Oscar Brings Wind and Rain to Southeastern Bahamas

Hurricane Oscar brought wind and rain to the Southeastern Bahamas early on Sunday.  At 8:00 a.m. EDT on Sunday the center of Hurricane Oscar was located at latitude 20.8°N and longitude 73.6°W which put the center about 20 miles (30 km) southwest of  Great Inagua.  Oscar was moving toward the west-southwest at 12 m.p.h. (19 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. (150 km/h).  The minimum surface pressure was 986 mb.

Hurricane Warnings are in effect for the Southeastern Bahamas.  Hurricane Warnings are also in effect for the North Coast of Cuban province of Holguin and the North Coast of Cuban province of Guantanamo to Punta Maisi.

Tropical Storm Warnings are in effect for the South Coast of Cuban province of Guantanamo and the North Coast of Cuban province of Las Tunas.

A Tropical Storm Watch is in effect for the North Coast of Cuban province of Camaguey.

The center of Hurricane Oscar passed over Great Inagua early on Sunday.  A very small eye with a diameter of 4 miles (6 km) was at the center of Oscar’s circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Short bands of showers and thunderstorms were revolving around the center of Hurricane Oscar.  Storms near the center of Oscar generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Oscar was very small.  Winds to hurricane force extended out 5 miles (8 km) on the northern side of Oscar’s circulation.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Hurricane Oscar.

Hurricane Oscar will move through an environment somewhat favorable for intensification during the next few hours.  Oscar will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southeastern end of an upper level ridge over Cuba.  The upper level ridge will produce northeasterly winds that will blow toward the top of Oscar’s circulation.  Those winds will cause some vertical wind shear.  The wind shear may be strong enough to prevent intensification.  Hurricane Oscar is likely to maintain its intensity during the next few hours.

Hurricane Oscar will move around the southern side of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Oscar toward the west-southwest during the next 24 hours.  On its anticipated track, Hurricane Oscar will reach eastern Cuba on Sunday afternoon.

Hurricane Oscar will continue to strong winds and locally heavy rain to the Southeastern Bahamas during the next  few hours. Oscar will also bring strong winds and heavy rain to eastern Cuba on Sunday night.  Heavy rain could cause flash floods in some locations.

Elsewhere, Tropical Depression Nadine was moving across southern Mexico. At 5:00 a.m. EDT on Sunday the center of Tropical Depression Nadine was located at latitude 16.8°N and longitude 91.8°W which put the center about 85 miles (135 km) east of Tuxtla Gutierrez, Mexico. Nadine was moving toward the west-southwest at 8 m.p.h. (14 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 1006 mb.

Hurricane Oscar Develops Rapidly Southeast of the Bahamas

Hurricane Oscar developed rapidly over the Atlantic Ocean southeast of the Bahamas on Saturday afternoon.  At 2:00 p.m. EDT on Saturday the center of Hurricane Oscar was located at latitude 21.4°N and longitude 70.6°W which put the center about 165 miles (265 km) east-southeast of the Southeastern Bahamas.  Oscar was moving toward the west at 12 m.p.h. (19 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. (150 km/h).  The minimum surface pressure was 989 mb.

A Hurricane Warning is in effect for the Turks and Caicos, and the Southeastern Bahamas.

A U.S. Air Force Reserve Hurricane Hunter reconnaissance plane found that a low pressure system over the Atlantic Ocean southeast of the Bahamas had rapidly developed into a hurricane on Saturday afternoon.  Based on data gather by the reconnaissance flight, the U.S. National Hurricane Center designated the system as Hurricane Oscar.

The circulation around Hurricane Oscar was very small.  A very small eye with a diameter of 4 miles (6 km) was at the center of Oscar’s circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Short bands of showers and thunderstorms were revolving around the center of Hurricane Oscar.  Storms near the center of Oscar generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Oscar was very small.  Winds to hurricane force extended out 5 miles (8 km) on the northern side of Oscar’s circulation.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Hurricane Oscar.

Hurricane Oscar will move through an environment mostly favorable for intensification during the next 24 hours.  Oscar will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the eastern end of an upper level ridge over the Bahamas.  The upper level ridge will produce northeasterly winds that will blow toward the top of Oscar’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Hurricane Oscar is likely to intensify during the next 24 hours.

Hurricane Oscar will move around the southern side of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Oscar toward the west during the next 24 hours.  On its anticipated track, Hurricane Oscar will move over the Turks and Caicos and the Southeastern Bahamas.  Oscar could approach eastern Cuba on Sunday night.

Hurricane Oscar will bring strong winds and locally heavy rain to the Turks and Caicos and the Southeastern Bahamas.  Heavy rain could cause flash floods in some locations.

Elsewhere, Tropical Storm Nadine brought strong winds and heavy rain to parts of Belize and the Yucatan Peninsula.  At 2:00 p.m. EDT on Saturday the center of Tropical Storm Nadine was located at latitude 17.6°N and longitude 88.5°W which put the center about 20 miles (30 km) west-northwest of Belize City, Belize.  Nadine 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 1003 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Belize City,, Belize to Cancun, Mexico.  The Tropical Storm Warning includes Cozumel.

Tropical Storm Nadine Forms East of Belize

Tropical Storm Nadine formed over the Northwest Caribbean Sea east of Belize on Friday night. At 8:00 a.m. EDT on Saturday the center of Tropical Storm Nadine was located at latitude 17.3°N and longitude 87.3°W which put the center about 60 miles (95 km) east of Belize City, Belize. Nadine was moving toward the west 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 1002 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Belize City,, Belize to Cancun, Mexico.  The Tropical Storm Warning includes Cozumel.

A low pressure system previously designated as Potential Tropical Cyclone Fifteen intensified during Friday night and the U.S. National Hurricane Center designated the system as Tropical Storm Nadine.  The circulation around Tropical Storm Nadine exhibited much more organization on Saturday morning.  More thunderstorms developed near the center of Nadine’s circulation.  The inner end of a rainband wrapped part of the way around the center of circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Nadine.  Storms near the center of Nadine generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the pressure to decrease.

The distribution of wind speeds in Tropical Storm Nadine was asymmetrical.  Winds to tropical storm force extended out 230 miles (370 km) in the northern side of Nadine’s circulation.  The winds in the southern side of Tropical Storm Nadine were blowing at less than tropical Storm force.

Tropical Storm Nadine will move through an environment favorable for intensification during the next few hours. Nadine will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the western end of an upper level ridge over the Caribbean Sea. The upper level ridge will produce southeasterly winds that will blow toward the top of the tropical disturbance.  Those winds will cause some vertical wind shear.  The wind shear will inhibit intensification, but the wind shear will not be enough to prevent the intensification.  Tropical Nadine will intensify during the next few hours.

Tropical Storm Nadine will move around the southern side of a high pressure system over the eastern United States.  The high pressure system will steer Nadine toward the west during the nest 24 hours.  On its anticipated track, Tropical Storm Nadine will make landfall on the coast of Belize in a few hours.

Tropical Storm Nadine will bring strong winds and heavy rain to parts of Belize and the Yucatan Peninsula.  Heavy rain is likely to cause flash floods in some locations.

Potential Tropical Cyclone Fifteen Prompts Watch for Belize

A disturbance over the Northwest Caribbean Sea designated as Potential Tropical Cyclone Fifteen prompted the issuance of a Tropical Storm Watch for a portion of the coast of Belize and the Yucatan Peninsula.  At 8:00 p.m. EDT on Friday the center of Potential Tropical Cyclone Fifteen was located at latitude 17.5°N and longitude 85.7°W which put the center about 165 miles (265 km) east of Belize City, Belize.  Potential Tropical Cyclone Fifteen was moving toward the west-northwest at 7 m.p.h. (11 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 1005 mb.

A Tropical Storm Watch is in effect for the portion of the coast from Belize, City, Belize to Tulum, Mexico.

A tropical disturbance over the Northwest Caribbean Sea exhibited more organization on Friday evening and the U.S. National Hurricane Center designated the system as Potential Tropical Cyclone Fifteen.  The tropical disturbance had a large counterclockwise circulation, but there was not a well defined low level center of circulation.  Thunderstorms were occurring in bands in the eastern and northern parts of the tropical disturbance.  Bands in the southern and western parts of the disturbance consisted primarily of showers and lower clouds.

Potential Tropical Cyclone Fifteen will move through an environment somewhat favorable for the formation of a tropical cyclone during the next 24 hours.  The tropical disturbance will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the western end of an upper level ridge over the Caribbean Sea.  The upper level ridge will produce southeasterly winds that will blow toward the top of the tropical disturbance.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit the formation of a tropical cyclone.  However, the wind shear may not be enough to prevent the formation of a tropical cyclone.  Potential Tropical Cyclone Fifteen could strengthen to a tropical storm on Saturday.

Potential Tropical Cyclone Fifteen will move around the southern side of a high pressure system over the eastern United States.  The high pressure system will steer the tropical disturbance toward the west-northwest during the nest 24 hours.  On its anticipated track, Potential Tropical Cyclone Fifteen will make landfall on the coast of Belize on Saturday afternoon.

Potential Tropical Cyclone Fifteen will bring gusty winds and heavy rain to parts of Belize and the Yucatan Peninsula.  Heavy rain is likely to cause flash floods in some locations.

Hurricane Milton Moves Away From Florida

Hurricane Milton moved eastward over the Atlantic Ocean away from Florida on Thursday morning.  At 11:00 a.m. EDT on Thursday the center of Hurricane Milton was located at latitude 29.1°N and longitude 78.5°W which put the center about 135 miles (220 km) east-northeast of Cape Canaveral, Florida.  Milton was moving toward the east-northeast at 20 m.p.h. (32 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. (150 km/h).  The minimum surface pressure was 983 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Sebastian Inlet, Florida to Edisto Beach, South Carolina.   A Tropical Storm Warning is in effect for the extreme Northwestern Bahamas including Grand Bahama Island, and the Abacos.

Hurricane Milton was making a transition to an extratropical cyclone as it moved away to the east of Florida on Thursday morning.  A warm front was forming in the eastern part of Milton’s circulation.  A cold front was forming to the south of the center of Hurricane Milton.  Thunderstorms were occurring in bands in the northern and eastern sides of Milton’s circulation.  Bands in the southern and western parts of Hurricane Milton consisted primarily of showers and lower clouds.

The transition to an extratropical cyclone was also causing the distribution of wind speeds around Hurricane Milton to become more asymmetrical.  Winds to hurricane force extended out 70 miles (110 km) in the northwestern quadrant of Milton’s circulation.  Winds to tropical storm force extended out 310 miles (500 km) from the center of Hurricane Milton.

Hurricane Milton will move through an environment unfavorable for intensification of a tropical cyclone during the next 24 hours.  Milton will move over water where the Sea Surface Temperatures are near 28°C.  However, an upper level trough over the eastern U.S. will produce strong westerly winds that will blow toward the top of Milton’s circulation.  Those winds will cause strong vertical wind shear.  The strong vertical wind shear will cause Hurricane Milton to complete a transition to an extratropical cyclone during the next 24 hours.

The upper level trough over the eastern U.S. will steer Hurricane Milton toward the east-northeast during the next 24 hours.  On its anticipated track, Hurricane Milton will move quickly away from Florida.  Milton could affect Bermuda on Friday as an extratropical cyclone.

Elsewhere over the Atlantic Ocean, Hurricane Leslie started to weaken.  At 11:00 a.m. EDT on Thursday the center of Hurricane Leslie was located at latitude 23.2°N and longitude 50.4°W which put the center about 1715 miles (2765 km) west-southeast of the Azores.  Leslie was moving toward the west-northwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 980 mb.

Hurricane Milton Brings Strong Winds and Heavy Rain to Florida

Hurricane Milton brought strong winds and heavy rain to Florida on Wednesday night.  At 11:00 P.m. EDT on Wednesday the center of Hurricane Milton was located at latitude 27.6°N and longitude 82.0°W which put the center about 75 miles (120 km) southwest of Orlando, Florida.  Milton was moving toward the east-northeast at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h).  The minimum surface pressure was 960 mb.

(137 km/h).  The Sarasota-Bradenton Airport reported a sustained wind speed of 69 m.p.h. (111 km/h) and a wind gust of 102 m.p.h. (171 km/h).

There were reports of almost two million customers without electricity.

The size of the circulation around Hurricane Milton increased as Milton approached the west coast of Florida.  Winds to hurricane force extend out 35 miles (55 km) from the center of Milton’s circulation.  Winds to tropical storm force extend out 250 miles (400 km) from the center of Hurricane Milton.

The Hurricane Intensity Index (HII) for Hurricane Milton is 17.8.  The Hurricane Size Index (HSI) is 16.8 and the Hurricane Wind Intensity Size Index (HWISI) is 34.6.  Hurricane Milton is almost as strong as Hurricane Sally was when Sally hit Alabama in 2020.  Milton is larger than Sally was.

Hurricane Milton will move around the southern part of an upper level trough over the eastern U.S.  The upper level trough will steer Milton toward the east-northeast during the next 24 hours.  On its anticipated track Hurricane Milton will move steadily across Central Florida.  Milton will move over the Atlantic Ocean east of Cape Canaveral on Thursday morning.

Even though Hurricane Milton  will weaken as it moves across Central Florida, Milton will continue bring strong winds and heavy rain to the region.

Hurricane Warnings are in effect for many of the counties in Central Florida.  Those Hurricane Warnings include Orlando.

.  Heavy rains will cause floods in some locations.

Flood Watches are in effect for much of the Florida Peninsula.

Milton will also continue to produce a storm surge the west coast of Florida until the winds subside on Thursday.

A Storm Surge Warning is in effect for the portion of the coast from Flamingo to the Anclote River, Florida.  The Storm Surge Warning includes Tampa Bay and Charlotte Harbor.  A Storm Surge Warning is also in effect for the portion of the coast from Sebastian Inlet, Florida to Altamaha Sound, Georgia.

Elsewhere over the Atlantic Ocean, Hurricane Leslie intensified to Category 2 on the Saffir-Simpson Scale east-northeast of the Northern Leeward Islands.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Leslie was located at latitude 22.6°N and longitude 49.3°W which put the center about 945 miles (1515 km) east-northeast of the Northern Leeward Islands.  Leslie was moving toward the northwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h).  The minimum surface pressure was 972 mb.

Hurricane Milton was weakening gradually on Wednesday afternoon, but Milton was still a major hurricane.  An upper level trough over the southern Mississippi River Valley was producing southwesterly winds that were blowing toward the top of Milton’s circulation.  Those winds were causing moderate vertical wind shear.  The upper level winds were also inhibiting the upper level divergence to the west of Hurricane Milton.  The wind shear was causing Hurricane Milton to weaken gradually.

A circular eye was present at the center of Hurricane Milton.  The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Thunderstorms were occurring in bands in the eastern and northern parts of Hurricane Milton.  Bands in the southern and western parts of Milton’s circulation consisted primarily of showers and lower clouds.  Storms near the center of Milton generated upper level divergence that pumped mass away to the northeast of the hurricane.

Even though Hurricane Milton is weakening, the circulation around Milton is getting larger.  Winds to hurricane force extend out 35 miles (55 km) from the center of Milton’s circulation.  Winds to tropical storm force extend out 250 miles (400 km) from the center of Hurricane Milton.

The Hurricane Intensity Index (HII) for Hurricane Milton is 22.1.  The Hurricane Size Index (HSI) is 16.8 and the Hurricane Wind Intensity Size Index (HWISI) is 38.9.  Hurricane Milton is similar in intensity to Hurricane Irma when Irma hit southwest Florida in 2017.  Milton is not as big as Irma was.

Hurricane Milton will move through an environment unfavorable for intensification during the next few hours.  Milton will move over water where the Sea Surface Temperatures are near 29°C.  However, the upper level trough over the southern Mississippi River Valley will continue to cause moderate to strong vertical wind shear.  The wind shear will cause Hurricane Milton to continue to weaken gradually during the next few hours.

The upper level trough over the southern Mississippi River Valley will steer Hurricane Milton toward the northeast east during the next 12 hours.  On its anticipated track, the center of Hurricane Milton will make landfall in a few hours on the west coast of Florida near or just to the south of Tampa.

Even though Hurricane Milton weakened today, Milton is still expected to be a major hurricane when it hits the west coast of Florida.   Milton will bring strong gusty winds and heavy rain to the west coast of Florida.   Milton will also bring strong winds and heavy rain to central Florida.

Hurricane Warnings are in effect for many of the counties in Central Florida.  Those Hurricane Warnings include Orlando.

Milton will be capable of causing major damage.  Heavy rains will cause floods in some locations. Widespread electricity outages are likely.

Flood Watches are in effect for much of the Florida Peninsula.

Milton will also produce a storm surge of up to 15 feet (4.5 meters) along the west coast of Florida.  The highest storm surge is likely to occur along the portion of the coast just to the south of Tampa.  A storm surge of 8 to 12 feet (2,4 to 3.7 meters) could occur in Tampa Bay.
