Hurricane Melissa Hits Jamaica

Hurricane Melissa hit Jamaica on Tuesday.  At 2:00 p.m. EDT on Tuesday the center of Hurricane Melissa was located at latitude 18.2°N and longitude 78.0°W which put the center about 20 miles 305 km) south-southwest of Montego Bay, Jamaica.  Melissa was moving toward the north-northeast at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 165 m.p.h. (265 km/h) and there were wind gusts to 195 m.p.h. (315 km/h).  The minimum surface pressure was 899 mb.

A Hurricane Warning is in effect for Jamaica.

Hurricane Warnings are in effect for the Cuban provinces of Granma, Santiago de Cuba, Guantanamo, Holguin, and Las Tunas.

Hurricane Warnings are in effect for the Central Bahamas and the Southeastern Bahamas.

A Tropical Storm Warning is in effect for Haiti.

A Tropical Storm Warning is in effect for the Cuban province of Camaguey.

A Tropical Storm Warning is in effect for the Turks and Caicos.

Hurricane Melissa was at Category 5 on the Saffir-Simpson Scale at the time of landfall.  The maximum sustained wind speed was 185 m.p.h. (300 km/h).  The minimum surface pressure was 892 mb.

The Hurricane Intensity Index (HII) for Hurricane Melissa at the time of landfall was 44.1.  The Hurricane Size Index (HSI) was 11.4 and the Hurricane Wind Intensity Size Index (HWISI) was 55.5.  Hurricane Melissa was similar in size and intensity to Hurricane Dorian when Dorian hit the Bahamas in 2019.

Hurricane Melissa was still a Category 5 hurricane on Tuesday afternoon.  A circular eye with a diameter of 17 miles (28 km) was at the center of Melissa’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 Hurricane Melissa.  Storms near the center of Melissa generated strong upper level divergence that pumped large quantities of mass away from the hurricane.  The removal of large amounts of mass in the upper levels was nearly balanced by a strong inflow of mass in the lower levels of the atmosphere.  The near balance of inflow and outflow of mass caused the surface pressure to remain nearly very low during the past few hours.

Winds to hurricane force extended out 30 miles (50 km) from the center of Hurricane Melissa.  Winds to tropical storm force extended out 195 miles (315 km) in the eastern half of Melissa’s circulation.  Winds to tropical storm force extended out 90 miles (145 km) in the western side of Hurricane Melissa.

An upper level trough over the southeastern U.S. will steer Hurricane Melissa toward the northeast during the next 24 hours.  On its anticipated track, the core of Hurricane Melissa will l move northeast across Jamaica.  Melissa will reach eastern Cuba early on Wednesday.  Hurricane Melissa will be over the Bahamas on Wednesday evening.

Hurricane Melissa will drop very heavy rain on Jamaica, Haiti and parts of the Dominican Republic.  Very heavy rain is likely to cause catastrophic floods in some locations.  Hurricane Melissa will also produce very strong winds in Jamaica.  Melissa will be capable of causing severe damage.  Widespread electricity outages are likely.  Infrastructure and transportation are likely to be severely damaged.  Melissa could produce a storm surge of up to 16 feet (5 meters) along the south coast of Jamaica.

Hurricane Melissa will also bring strong winds and locally heavy rain to eastern Cuba, the Central and Southeastern Bahamas, and the Turks and Caicos.  Heavy rain is likely to cause flash floods in some locations.  Widespread electricity outages are also likely in eastern Cuba.

Hurricane Melissa Nears Jamaica

The core of Hurricane Melissa was nearing southwestern Jamaica on Tuesday morning.  At 10:00 a.m. EDT on Tuesday the center of Hurricane Melissa was located at latitude 17.7°N and longitude 78.1°W which put the center about 45 miles (75 km) south-southeast of Negril, Jamaica.  Melissa was moving toward the north-northeast at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 185 m.p.h. (300 km/h) and there were wind gusts to 220 m.p.h. (355 km/h).  The minimum surface pressure was 892 mb.

Winds to tropical storm force were already occurring in Jamaica even though the core of Hurricane Melissa was still southwest of Jamaica.  A weather station at the Norman Manley International Airport in Kingston reported a sustained wind speed of 43 m.p.h. (69 km/h) and a wind gust of 59 m.p.h. (93 km/h).  A weather station at the Sangster International Airport in Montego Bay reported a sustained wind speed of 38 m.p.h. (61 km/h) and a wind gust of 54 m.p.h. (87 km/h).  Heavy rain was already falling over parts of Jamaica.

The core of dangerous Hurricane Melissa was nearing the coast of southwestern Jamaica on Tuesday morning.  A circular eye with a diameter of 12 miles (19 km) was at the center of Melissa’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 Hurricane Melissa.  Storms near the center of Melissa generated strong upper level divergence that pumped large quantities of mass away from the hurricane.  The removal of large amounts of mass in the upper levels was nearly balanced by a strong inflow of mass in the lower levels of the atmosphere.  The near balance of inflow and outflow of mass caused the surface pressure to remain nearly steady during the past few hours.

Winds to hurricane force extended out 30 miles (50 km) from the center of Hurricane Melissa.   Winds to tropical storm force extended out 195 miles (315 km) in the eastern half of Melissa’s circulation.  Winds to tropical storm force extended out 90 miles (145 km) in the western side of Hurricane Melissa.

The Hurricane Intensity Index (HII) for Hurricane Melissa is 44.1.  The Hurricane Size index (HSI) is 11.4 and the Hurricane Wind Intensity Size Index (HWISI) is 55.5.  Hurricane Melissa is similar in size and intensity to Hurricane Dorian when Dorian hit the Bahamas in 2019.

Hurricane Melissa will move through an environment favorable for a very powerful hurricane during the few hours until it makes landfall in Jamaica.  Melissa will move over water where the Sea Surface Temperatures are near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Melissa is likely to maintain its intensity until it makes landfall in Jamaica unless an eyewall replacement cycle occurs.  If the inner end of a rainband wraps around the existing eye and eyewall, then the formation of concentric eyewalls would cause Melissa to start to weaken.

An upper level trough over the southeastern U.S. will steer Hurricane Melissa toward the northeast during the next 24 hours.  On its anticipated track, the core of Hurricane Melissa will reach southwestern Jamaica on Tuesday morning.  Melissa will move northeast across Jamaica during much of Tuesday.  Hurricane Melissa will reach eastern Cuba early on Wednesday.

Hurricane Melissa will drop very heavy rain on Jamaica, Haiti and parts of the Dominican Republic.  Very heavy rain is likely to cause catastrophic floods in some locations.  Hurricane Melissa will also produce very strong winds in Jamaica.  Melissa will be capable of causing severe damage.  Widespread electricity outages are likely.  Infrastructure and transportation are likely to be severely damaged.  Melissa could produce a storm surge of up to 16 feet (5 meters) along the south coast of Jamaica.

Hurricane Melissa will also bring strong winds and locally heavy rain to eastern Cuba, the Central and Southeastern Bahamas, and the Turks and Caicos.  Heavy rain is likely to cause flash floods in some locations.  Widespread electricity outages are also likely in eastern Cuba.

Tropical Storm Rafael Brings Wind and Rain to Jamaica

Tropical Storm Rafael was bringing wind and rain to Jamaica on Tuesday morning.  The center of Rafael was just southwest of Jamaica.  At 7:00 a.m. EST on Tuesday the center of Tropical Storm Rafael was located at latitude 17.4°N and longitude 78.4°W which put the center about 80 miles (130 km) south-southwest of Montego Bay, Jamaica.  Rafael was moving toward the northwest 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. (120 km/h).  The minimum surface pressure was 993 mb.

A Hurricane Warning was in effect for Grand Cayman, Little Cayman, and Cayman Brac.  A  Hurricane Warning was in effect for the Cuban provinces of Pinar del Rio, Artemisa, La Habana, Mayabeque, Matanzas, and the Isle of Youth.

A Tropical Storm Warning was in effect for Jamaica. A Tropical Storm Warning was in effect for the Cuban provinces of Villa Clara, Cienfuegos, Sancti Spiritis, and Ciego de Avila.

A Tropical Storm Watch was in effect for the Florida Keys from Key West to Channel 5 Bridge.  A Tropical Storm Watch was in effect for the Dry Tortugas.  A Tropical Storm Watch was in effect for the Cuban provinces of Camaguey and Las Tunas.

Tropical Storm Rafael was strengthening on Tuesday morning as it passed near Jamaica.  The inner end of a rainband wrapped around the western and southern sides of the center of Rafael’s circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Rafael.  Storms near the center of Rafael generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speeds around Tropical Storm Rafael was asymmetrical.  Winds to tropical storm force extended out 105 miles (165 km) in the eastern side of Rafael’s circulation.  The winds in the western side of Tropical Storm Rafael were blowing at less than tropical storm force.

Tropical Storm Rafael will move through an environment favorable for intensification during the next 24 hours.  Rafael will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge over the Caribbean Sea.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. Tropical Storm Rafael will intensify during the next 24 hours.  Rafael could intensify rapidly at times.  Tropical Storm Rafael is likely to strengthen to a hurricane by Tuesday night.

Tropical Storm Rafael will move around the southwestern part of a high pressure system over the western Atlantic Ocean.  The high pressure system will steer Rafael toward the northwest during the next 24 hours.  On its anticipated track, the center of Tropical Rafael will reach the Cayman Islands by Tuesday night.  Rafael is likely to reach western Cuba by Wednesday afternoon.

Tropical Storm Rafael will continue to bring strong winds and heavy rain Jamaica for the rest of Tuesday.  Heavy rain is likely to cause floods in some locations.  Rafael is likely to be a hurricane when it moves over the Cayman Islands.  Rafael will bring strong winds and heavy rain to the Cayman Islands.  It could also cause a storm surge of up to 7 feet (2 meters) in the Cayman Islands.  Rafael will be a hurricane when it reaches western Cuba.  Strong winds could cause widespread electricity outages in Cuba.  Heavy rain could cause flash floods in some locations.

Tropical Storm Grace Brings Wind and Rain to Jamaica

Tropical Storm Grace brought wind and rain to Jamaica on Tuesday. At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Grace was located at latitude 18.5°N and longitude 77.5°W which put it about 25 miles (40 km) east of Montego Bay, Jamaica. Grace was moving toward the west at 15 m.p.h. (24 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 1005 mb.

A Hurricane Watch was in effect for the portion of the coast from Cabo Catoche to Punta Allen, Mexico. Tropical Storm Warnings were in effect for Jamaica, the Cayman Islands and the Cuban provinces of Santiago de Cuba, Granma, Las Tunas and Camaguey. Tropical Storm Watches were in effect for the Cuban provinces of Ciego de Avila, Sancti Spiritus, Cinefuegos, Matanzas, Pinar del Rio and Isla de la Juventud.

The center of Tropical Storm Grace was moving along the northern coast of Jamaica on Tuesday afternoon. Grace was causing gusty winds over Jamaica and it was also dropping heavy rain. Tropical Storm Grace strengthened earlier on Tuesday as it approached Jamaica. More thunderstorms developed near the center of circulation. Bands of showers and thunderstorms were revolving around the center of Grace. Storms near the center generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 70 miles (110 km) on the eastern side of Grace. The winds in the western half of the circulation were blowing mostly at less than tropical storm force.

Tropical Storm Grace will move south of a subtropical high pressure system over the Atlantic Ocean. The high will steer Grace toward the west during the next several days. On its anticipated track Tropical Storm Grace will move across Jamaica during the next few hours. Grace could reach the Cayman Islands early on Wednesday. Grace could approach the Yucatan Peninsula on Wednesday night.

Tropical Storm Grace is not likely to strengthen during the next few hours while the center of circulation is near the northern coast of Jamaica. Grace will move through an environment favorable for intensification after it moves west of Jamaica. Grace will move over water where the Sea Surface Temperatures are near 30°C. It will move under the southern side of an upper level ridge centered near Florida. The ridge will produce easterly winds that will blow toward the top of Grace’s circulation. Those winds will cause some vertical wind shear, but the shear will be too small to prevent intensification. Tropical Storm Grace could strengthen to a hurricane over the northwestern Caribbean Sea. A period of rapid intensification could occur if an inner core with an eye and an eyewall forms at the center of Grace.

Elsewhere, Tropical Depression Fred was dropping heavy rain over parts of the southeastern U.S. and Tropical Storm Henri was strengthening south of Bermuda.

At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Fred was located at latitude 33.4°N and longitude 84.7°W which put it about 30 miles (50 km) south-southwest of Atlanta, Georgia. Fred was moving toward the north-northeast at 17 m.p.h. (28 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 2:00 p.m. EDT on Tuesday the center of Tropical Storm Henri was located at latitude 30.4°N and longitude 64.3°W which put it about 143 miles (215 km) south-southeast of Bermuda. Henri was moving toward the west-southwest at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 1000 mb. A Tropical Storm Watch was in effect for Bermuda.
