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.
