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.

Tropical Storm Ernesto Moves Away from Bermuda

Tropical Storm Ernesto moved away from Bermuda on Saturday evening.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Ernesto was located at latitude 33.9°N and longitude 63.3°W which put the center about 140miles (220 km) northeast of Bermuda.  Ernesto was moving toward the north-northeast at 8 m.p.h. (13 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 978 mb.

A Tropical Storm Warning was in effect for Bermuda.

Former Hurricane Ernesto weakened to a tropical storm on Saturday evening.  Drier air wrapped all of the way around Ernesto’s circulation.  The drier air caused many of the remaining thunderstorms in Tropical Storm Ernesto to dissipate.  Thunderstorms were still occurring in the northern portion of the former eyewall.  The remnant of former Hurricane Ernesto’s large eye was also visible on satellite imagery.  The bands revolving around the center of Ernesto’s circulation consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Ernesto was large.  Winds to tropical storm force extended out 230 miles (370 km) from the center of Ernesto’s circulation.

Tropical Storm Ernesto will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Ernesto will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southern portion of an upper level trough off the east coast of the U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Ernesto’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will be less on Sunday.  The wind shear and the drier air In Ernesto’s circulation will inhibit intensification.  However, Tropical Storm Ernesto could strengthen a little during the next 24 hours even with the vertical wind shear and drier air.

Tropical Storm Ernesto will move around the western side of a subtropical high pressure system over the Atlantic Ocean.  The high pressure system will steer Ernesto toward the north-northeast during the next 24 hours.  An upper level trough over the Great Lakes will steer Ernesto toward the northeast more quickly on Monday.  Tropical Storm Ernesto could approach southeastern Newfoundland on Monday night.

Hurricane Ernesto Hits Bermuda

Hurricane Ernesto hit Bermuda early on Saturday.  At 8:00 a.m. EDT on Saturday the center of Hurricane Ernesto was located at latitude 32.6°N and longitude 64.6°W which put the center about 15 miles (25 km) north-northeast of Bermuda.    Ernesto was moving toward the north-northeast at 9 m.p.h. (15 km/h).   The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).   The minimum surface pressure was 974 mb.

A Hurricane Warning was in effect for Bermuda.

The center of Hurricane Ernesto passed over Bermuda early on Saturday.  A weather station at the L.F. Wade International airport reported a sustained wind speed of 61 m.p.h. (98 km/h) and a wind gust of 84 m.p.h. (135 km/h).  There were reports of widespread electricity outages in Bermuda.

The size of the circulation around Hurricane Ernesto was large when Ernesto moved over Bermuda.  Winds to hurricane force extended out 70 miles (110 km) from the center of Ernesto’s circulation.  Winds to tropical storm force extended out 240 miles (390 km) from the center of Hurricane Ernesto.

The Hurricane Intensity Index (HII) was 12.7.  The Hurricane Size Index (HSI) was 22.3 and the Hurricane Wind Intensity Size Index (HWISI) was 35.0.  Hurricane Ernesto was similar in intensity to Hurricane Irene when Irene hit North Carolina in 2011.  Ernesto was not quite as large as Irene was.

Drier air was pulled around the southern side of Hurricane Ernesto as it approached Bermuda.  The drier air caused many of the thunderstorms in the western and southern parts of Ernesto’s circulation to weaken.  Bands in the western and southern sides of Hurricane Ernesto consisted primarily of showers and lower clouds.  Thunderstorms were still occurring in bands in the eastern and northern parts of Ernesto.  Storms near the center of Ernesto’s circulation generated upper level divergence that pumped mass away to the northeast of the hurricane.

Hurricane Ernesto will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Ernesto will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern portion of an upper level trough off the east coast of the U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Ernesto’s circulation.  Those winds will cause moderate vertical wind shear.  The drier air In Ernesto’s circulation will inhibit intensification.  Hurricane Ernesto is likely to maintain its intensity during the next 24 hours.

Hurricane Ernesto will move around the western side of a subtropical high pressure system over the Atlantic Ocean.  The high pressure system will steer Ernesto toward the north-northeast during the next 24 hours.  On its anticipated track, Hurricane Ernesto will move away from Bermuda on Saturday.  An upper level trough over the Great Lakes will steer Ernesto toward the northeast more quickly on Sunday.  Hurricane Ernesto could approach Newfoundland on Monday night.

The wind speeds will diminish in Bermuda as Hurricane Ernesto moves farther away on Saturday.

 

 

Hurricane Ernesto Approaches Bermuda

Hurricane Ernesto was approaching Bermuda on Friday afternoon.  At 5:00 p.m. EDT on Friday the center of Hurricane Ernesto was located at latitude 30.6°N and longitude 65.6°W which put the center about 125 miles (200 km) south-southwest of Bermuda.   Ernesto was moving toward the northeast at 13 m.p.h. (20 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 969 mb.

A Hurricane Warning was in effect for Bermuda.

A circular eye with a diameter of 60 miles (95 km) was present at the center of Ernesto’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 Ernesto’s circulation.  Storms near the center generated upper level divergence that pumped mass away from the hurricane.  The removal of mass in the upper levels was balanced by the inflow of mass in the lower levels.

The size of the circulation around Hurricane Ernesto was large.  Winds to hurricane force extended out 70 miles (110 km) from the center of Ernesto’s circulation.  Winds to tropical storm force extended out 275 miles (445 km) from the center of Hurricane Ernesto.

The Hurricane Intensity Index (HII) was 16.5.  The Hurricane Size Index (HSI) was 24.8 and the Hurricane Wind Intensity Size Index (HWISI) was 41.3.  Hurricane Ernesto is similar in size to Hurricane Gustav when Gustav hit Louisiana in 2008.  Ernesto is not quite as strong as Gustav  was.

Hurricane Ernesto will move through an environment that will become less favorable for intensification during the next 24 hours.  Ernesto will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern portion of an upper level trough off the east coast of the U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Ernesto’s circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification but Hurricane Ernesto is likely to maintain its intensity during the next 24 hours.

Hurricane Ernesto will move around the western side of a subtropical high pressure system over the Atlantic Ocean.  The high pressure system will steer Ernesto toward the north during the next 24 hours.  On its anticipated track, the center of Hurricane Ernesto will move near Bermuda early on Saturday morning.

Hurricane Ernesto will bring strong winds and heavy rain to Bermuda.  The strong winds will be capable of causing serious damage.  Heavy rain could cause flash floods.

 

Hurricane Ernesto Intensifies to Cat. 2

Hurricane Ernesto intensified to Category 2 on the Saffir-Simpson Scale on Thursday evening.  At 11:00 p.m. EDT on Thursday the center of Hurricane Ernesto was located at latitude 27.1°N and longitude 68.1°W which put the center about 410 miles (660 km) south-southwest of Bermuda.  Ernesto was moving toward the north-northeast at 14 m.p.h. (22 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 968 mb.

A Hurricane Warning was in effect for Bermuda.

A U.S. Air Force Reserve Hurricane Hunter aircraft found that Hurricane Ernesto has strengthened to Category 2 on the Saffir-Simpson Scale on Thursday evening.  A circular eye with a diameter of 45 miles (75 km) was present at the center of Ernesto’s circulation.  The eye was surrounded by a broken 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 Ernesto’s circulation.  Storms near the center generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the pressure to decrease.

The size of the circulation around Hurricane Ernesto increased on Thursday.  Winds to hurricane force extended out 60 miles (95 km) from the center of Ernesto’s circulation.  Winds to tropical storm force extended out 260 miles (420 km) from the center of Hurricane Ernesto.

The Hurricane Intensity Index (HII) was 16.5.  The Hurricane Size Index (HSI) was 16.7 and the Hurricane Wind Intensity Size Index (HWISI) was 33.2.  Hurricane Ernesto was similar in intensity to Hurricane Idalia when Idalia hit Florida in 2023.  Ernesto is larger than Idalia was.

Hurricane Ernesto will move through an environment favorable for intensification during the next 24 hours.  Ernesto will move over water where the Sea Surface Temperatures are 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 Ernesto is likely to continue to intensify during the next 24 hours.

Hurricane Ernesto will move around the western side of a subtropical high pressure system over the Atlantic Ocean.  The high pressure system will steer Ernesto toward the north during the next 24 hours.  On its anticipated track, Hurricane Ernesto will approach Bermuda on Friday night.  The center of Ernesto will be near Bermuda on Saturday morning.

Hurricane Ernesto will bring strong winds and heavy rain to Bermuda.  The strong winds will be capable of causing serious damage.  Heavy rain could cause flash floods.

Tropical Storm Tammy Moves Away From Bermuda

Tropical Storm Tammy moved away from Bermuda on Saturday. At 11:00 a.m. EDT on Saturday the center of Tropical Storm Tammy was located at latitude 33.3°N and longitude 58.7°W which put it about 360 miles (580 km) east-northeast of Bermuda. Tammy was moving toward the east at 12 m.p.h. (19 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 985 mb.

Tropical Storm Tammy weakened on Saturday as it moved under the southern extent of the upper level westerlies in the middle latitudes. The upper level westerly winds blew toward the top of Tammy’s circulation and they also caused strong vertical wind shear. The wind shear caused the distribution of thunderstorms in Tropical Storm Tammy to become asymmetrical. Thunderstorms were occurring in bands in the eastern side of Tammy’s circulation. Bands in the western half of Tropical Storm Tammy consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 140 miles (220 km) from the center of Tammy’s circulation.

Tropical Storm Tammy will move through an environment that will be unfavorable for intensification during the next 24 hours. Tammy will move over water where the Sea Surface Temperatures are near 25°C. The upper level westerly winds will continue to cause strong vertical wind shear. The combination of marginal Sea Surface Temperatures and strong vertical wind shear will continue to create an environment unfavorable for intensification during the next 24 hours.

Tropical Storm Tammy will move around the northern side of a high pressure system over the eastern Atlantic Ocean. The high pressure system will steer Tammy toward the east during the next 24 hours. On its anticipated track, Tropical Storm Tammy will move farther away from Bermuda.

Tammy Makes a Transition Back to a Tropical Storm

Former Hurricane Tammy made a transition back to a tropical storm east of Bermuda on Friday morning. At 11:00 a.m. EDT on Friday the center of Tropical Storm Tammy was located at latitude 32.2°N and longitude 61.1°W which put it about 215 miles (350 km) east of Bermuda. Tammy was moving toward the northwest at 3 m.p.h. (5 km/h). The maximum sustained wind speed was 65 m.p.h. (95 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 988 mb.

Former Hurricane Tammy made a transition from an extratropical cyclone back to a tropical storm east of Bermuda on Friday morning. The circulation of Tropical Storm Tammy became separated from the occluded front that had formed on Thursday. More thunderstorms formed near the center of Tammy’s circulation. The circulation became more symmetrical and it had the appearance of a tropical storm on visible satellite images. Based on the changes in the circulation’s structure, the U.S. National Hurricane Center designated Tammy as a tropical storm again.

Bands of showers and thunderstorms were revolving around the center of Tropical Storm Tammy. Storms near the center generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 205 miles (335 km) in the northern side of Tammy’s circulation. Winds to tropical storm force extended out 90 miles in the southern side of the circulation.

Tropical Storm Tammy will be in an environment somewhat favorable for intensification during the next 24 hours. Tammy will move over water where the Sea Surface Temperatures are near 26°C. It will be in a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Tammy could intensify back to a hurricane during the next 24 hours.

Tropical Storm Tammy will be in an area where the steering level winds are weak during the next 12 hours. Tammy could meander east of Bermuda during the rest of Friday. A high pressure system centered southeast of Bermuda will steer Tropical Storm Tammy toward the east during the weekend. On its anticipated track, Tropical Storm Tammy will move away from Bermuda during the weekend.
