Hurricane Milton rapidly intensified to Category 5 on the Saffir-Simpson Scale on Monday morning.  A circular eye with a diameter of 17 miles (28 km) was at the center of Milton’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Milton.  Storms near the center of Milton’s circulation generated strong upper level divergence that pumped large quantities of mass away from the hurricane.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

Hurricane Milton was a small hurricane.  Winds to hurricane force extended out 30 miles (50 km) from the center of Milton’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Hurricane Milton.

The Hurricane Intensity Index (HII) for Hurricane Milton is 35.0.  The Hurricane Size Index (HSI) is 10.6 and the Hurricane Wind Intensity Size Index (HWISI) is 45.6. Hurricane Milton is as strong as Hurricane Michael when Michael hit Northwest Florida in 2018.  Milton is not quite as big as Michael was.

Hurricane Milton move through an environment favorable for intensification during the next 24 hours.  Milton will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge over the Gulf of Mexico.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear. Hurricane Milton will intensify during the next 24 hours.  Milton could continue to intensify rapidly for a few more hours.

An upper level trough over the central U.S. will start to steer Milton more quickly toward the northeast during the next 24 hours.  On its anticipated track, Hurricane Milton will reach the west coast of Florida on Wednesday.  Milton will be a major hurricane when it reaches Florida.

Hurricane Milton will 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. 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.

A Storm Surge Watch is in effect for the portion of the coast from Flamingo to the Mouth of the Suwanee River, Florida.  The Storm Surge Watch includes Tampa Bay and Charlotte Harbor.

The circulation around Hurricane Helene was large.  Winds to hurricane force extended out 60 miles (95 km) from the center of Helene’s circulation.  Winds to tropical storm force extended out 345 miles (555 km) in the eastern side of Hurricane Helene.  Winds to tropical storm force extended out 140 miles (225 km) in the western side of Helene’s circulation.

The Hurricane Intensity Index (HII) is 22.1.  The Hurricane Size Index (HSI) is 17.6 and the Hurricane Wind Intensity Size Index (HWISI) 39.7.  Hurricane Helene is stronger than Hurricane Irma was when Irma hit southwest Florida in 2017.  However, Helene is not as big as Irma was.

Hurricane Helene will move through an environment favorable for intensification during the next few hours.  Helene will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over the eastern Gulf of Mexico.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Hurricane Helene is likely to intensify during the next few hours.  Helene could strengthen to Category 4 on the Saffir-Simpson Scale.

Hurricane Helene will move around the western end of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Helene toward the north-northeast during the next 24 hours.  On its anticipated track, Hurricane Helene will make landfall on the coast of northern Florida at Apalachee Bay Thursday evening.  Helene will be a major hurricane when it reaches the coast.

Hurricane Helene will be a major hurricane when it reaches northern Florida.  Helene will be a large and dangerous hurricane.  Hurricane Helene will bring strong winds and heavy rain to northern Florida.  Heavy rain is likely to cause floods.

Flood Watches are in effect for Florida, eastern Alabama, Georgia, western South Carolina, western North Carolina and eastern Tennessee.

Helene could also cause a storm surge of up to 20 feet (6.1 meters) along portions of the west coast of Florida.

A Storm Surge Warning is in effect for the portion of the coast from Mexico Beach to Flamingo, Florida.  The Storm Surge Warning includes Tampa Bay and Charlotte Harbor.

An upper level trough over the Mississippi River Valley will steer Hurricane Helene quickly toward the north-northeast after it makes landfall.  Since the circulation around Helene is so large, Hurricane Helene will produce hurricane force winds in inland locations as well.

Hurricane Warnings are in effect for parts of northern Florida, southeastern Alabama and southwestern Georgia.  The Hurricane Warnings include Tallahassee, Florida and Macon, Georgia.

Tropical Storm Warnings are in effect for the Florida Peninsula, northwest Florida eastern Alabama, northern and eastern Georgia, all of South Carolina, southwestern North Carolina, and southeastern Tennessee.  The Tropical Storm Warnings include Atlanta, Georgia and Charleston, South Carolina.

Hurricane Helene is likely to cause widespread electricity outages as it moves inland over the southeastern U.S.

Hurricane Helene Strengthens to Cat. 2

Hurricane Helene strengthened to Category 2 on the Saffir-Simpson Scale over the eastern Gulf of Mexico on Thursday morning.  At 8:00 a.m. EDT on Thursday the center of Hurricane Helene was located at latitude 24.5°N and longitude 85.9°W which put the center about 365 miles (585 km) south of Apalachicola, Florida.  Helene was moving toward the north-northeast 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 960 mb.

The circulation around Hurricane Helene was large.  Winds to hurricane force extended out 60 miles (95 km) from the center of Helene’s circulation.  Winds to tropical storm force extended out 345 miles (555 km) in the eastern side of Hurricane Helene.  Winds to tropical storm force extended out 140 miles (225 km) in the western side of Helene’s circulation.

The Hurricane Intensity Index (HII) is 16.5.  The Hurricane Size Index (HSI) is 17.6 and the Hurricane Wind Intensity Size Index (HWISI) 34.1.  Hurricane Helene is similar in intensity to Hurricane Idalia that hit northeast Florida in 2023.  However, Helene is much bigger than Idalia was.  Helene is still intensifying.  So, Helen will be stronger than Idalia was when i reaches the coast.

Hurricane Helene will move through an environment favorable for intensification during the next 12 hours.  Helene will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over the eastern Gulf of Mexico.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Hurricane Helene will intensify during the next 12 hours.  Helene is likely to strengthen to a major hurricane by Thursday afternoon.  Helene could intensify rapidly at times.

A U.S. Air Force Reserve Hurricane Hunter aircraft found that former Tropical Storm Helene had strengthened to a hurricane on Wednesday morning.  The inner end of a rainband wrapped around the northern, western and southern sides of the center of Helene’s circulation.  An eye appeared to be forming at the center of Hellene.  Bands of showers and thunderstorms were revolving around the core of Hurricane Helene.  Storms near the core generated strong upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

Winds to hurricane force extended out 25 miles (40 km) from the center of Hurricane Helene.  Winds to tropical storm force extended out 275 miles (445 km) in the eastern side of Helene’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) in the eastern side of Hurricane Helene.

Hurricane Helene will move through an environment favorable for intensification during the next 24 hours.  Helene will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over the western Gulf of Mexico and the northwestern Caribbean Sea.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Hurricane Helene will intensify during the next 24 hours.  Helene is likely to strengthen to a major hurricane by Thursday afternoon.  Helene could intensify rapidly after an inner core with an eye and an eyewall is fully developed.

Hurricane Helene will move around the western end of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Helene toward the north during the next 24 hours.  On its anticipated track, Hurricane Helene will approach northern Florida on Thursday afternoon.  Helene is likely to be a major hurricane when it reaches the northeastern Gulf of Mexico.

Hurricane Helene is likely to be a major hurricane when it approaches northern Florida on Thursday.  Helene will bring strong winds and heavy rain to northern Florida.  Heavy rain is likely to cause floods.
