Hurricane Rafael hit western Cuba late on Wednesday afternoon. At 4:00 p.m. EST on Wednesday the center of Hurricane Rafael was located at latitude 22.6°N and longitude 82.7°W which put the center about 45 miles (75 km) south-southwest of Havana, Cuba. Rafael was moving toward the northwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 140 m.p.h. (220 km/h). The minimum surface pressure was 950 mb.
A Hurricane Warning is in effect for the Cuban provinces of Pinar del Rio, Artemisa, La Habana, Mayabeque, Matanzas, and the Isle of Youth.
A Tropical Storm Warning is in effect for the Cuban provinces of Villa Clara, and Cienfuegos. A Tropical Storm Warning is in effect for the Florida Keys from Key West to Channel 5 Bridge. A Tropical Storm Warning is in effect for the Dry Tortugas.
Hurricane Rafael intensified to a major hurricane on Wednesday before it hit western Cuba. Concentric eyewalls formed in the core of Rafael’s circulation. An eyewall replacement cycle started, but the inner eyewall was still intact when Hurricane Rafael hit western Cuba. Since the inner eyewall was still intact, Rafael did not weaken before it hit Cuba.
Bands of showers and thunderstorms were revolving around the concentric eyewalls. Storms near the core of Rafael generated upper level divergence that pumped mass away from the hurricane. The removal of mass caused the surface pressure to decrease.
The circulation around Hurricane Rafael was small. Wind to hurricane force extended out 30 miles (50 km) from the center of Rafael’s circulation. Winds to tropical storm force extended out 115 miles (185 km) in the eastern side of Hurricane Rafael. Winds to tropical storm force extended out 60 miles (95 km) in the western side of Rafael.
The Hurricane Intensity Index (HII) for Hurricane Rafael was 20.6. The Hurricane Size Index (HSI) was 8.8 and the Hurricane Wind Intensity Size Index (HWISI) was 29.4. Hurricane Rafael was similar in intensity to Hurricane Delta when Delta hit Louisiana in 2020. Rafael was not as big as Delta was.
Hurricane 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 west-northwest during the next 24 hours. On its anticipated track, the center of Hurricane Rafael will move across western Cuba during the next few few hours. Rafael will move over the southeastern Gulf of Mexico on Thursday.
Hurricane Rafael will bring strong winds and heavy rain to western Cuba. Strong winds could cause widespread electricity outages in Cuba. Heavy rain will cause flash floods in some locations. Rafael could cause a storm surge of up to 10 feet (3 meters) along the south coast of western Cuba. Hurricane Rafael will be capable of causing localized major damage.
Hurricane Rafael will weaken as it moves across western Cuba. Rafael will move into an environment somewhat favorable for intensification after it moves north of Cuba. Rafael will move over water where the Sea Surface Temperatures are near 29°C. It will move under the eastern periphery of a large upper level trough that extends from the North Central U.S. to the Southwest U.S. The upper level trough will produce southwesterly winds that will blow toward the top of Rafael’s circulation. Those winds will cause the vertical wind shear to increase but the wind shear may not be enough to prevent intensification. Hurricane Rafael will could intensify on Thursday after it moves north of Cuba.
