A Hurricane Watch was issued for a portion of the west coast of Florida because of Tropical Storm Elsa. At 5:00 a.m. EDT on Tuesday the center of Tropical Storm Elsa was located at latitude 24.1°N and longitude 82.4°W which put it about 50 miles (80 km) southwest of Key West, Florida. Elsa was moving toward the north-northwest at 12 m.p.h. (19 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 1007 mb.
A Hurricane Watch was issued for the portion of the coast from Egmont Key to Steinhatchee River, Florida. A Tropical Storm Warning was in effect for the Florida Keys from Craig Key to the Dry Tortugas. A Tropical Storm Warning was also in effect for the portion of the coast from Flamingo to Ochlockonee River, Florida. That warning included Naples, Ft. Myers, Tampa, St. Petersburg and Tampa Bay. Tropical Storm Warnings remained in effect for the Cuban provinces of Matanzas, Mayabeque, Havana and Artemisa. A Tropical Storm Watch was in effect for the portion of the coast from Ochlockonee River to Indian Pass, Florida. A Tropical Storm Watch was issued for the portion of the coast from the Mouth of the St. Marys River, Georgia to the South Santee River, South Carolina.
The center of Tropical Storm Elsa was southwest of Key West, Florida on Tuesday morning. The National Weather Service office in Key West reported a wind gust of 47 m.p.h. (76 km/h). The distribution of thunderstorms around Elsa continued to be asymmetrical. The strongest thunderstorms were occurring in bands on the eastern side of Tropical Storm Elsa. Bands on the western side of the storm consisted primarily of showers and lower clouds. Storms near the center or Elsa generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 70 miles from the center of circulation.
Tropical Storm Elsa will move through an environment somewhat favorable for intensification during the next 18 hours. Elsa will move over water where the Sea Surface Temperatures are near 29°C. It will move under the western end of an upper level ridge. The ridge will produce southwesterly winds that will blow toward the top of Tropical Storm Elsa. Those winds will cause some vertical wind shear that will inhibit intensification. However, the southwesterly winds may also increase upper level divergence to the northeast of Elsa. Additional upper level divergence could cause the surface pressure to decrease on Tuesday. Tropical Storm Elsa could intensify on Tuesday and there is a chance that Elsa could strengthen to a hurricane.
Tropical Storm Elsa will move around the western end of the subtropical high pressure system over the Atlantic Ocean during the next several days. The high will steer Elsa toward the north on Tuesday. Tropical Storm Elsa will turn toward the northeast on Wednesday when it reaches the westerly winds in the middle latitudes. On its anticipated track the center of Elsa will pass west of the Key West on Tuesday morning. The center of Tropical Storm Elsa could pass west of Tampa on Tuesday night. The stronger winds and heavy rain will occur on the eastern side of Elsa. Heavy rain could cause flash floods in some locations. Winds pushing water toward the coast could cause a storm surge of up to six feet (two meters) in Tampa Bay. Tropical Storm Elsa could cause a storm surge of 2 to 5 feet (0.6 to 1.6 m) in the Florida Keys and along the west coast of Florida. A higher storm surge could occur near where the center of Elsa makes landfall. Gusty winds could cause power outages in the Florida Keys and on the Florida peninsula. Elsa will continue to drop heavy rain over parts of Cuba as rainbands on the southern side of the circulation move across the regions
