Tropical Storm Isaac stronger as it heads towards Haiti

MIAMI, USA — An Air Force Reserve hurricane hunter aircraft has reported that Tropical Storm Isaac was a little stronger as it headed slowly west through the Caribbean on Friday morning towards Haiti and the Dominican Republic, after drenching parts of Puerto Rico with heavy rain.

Thousands of people in Haiti are still living in tents after the devastating earthquake more than two years ago.

Isaac was forecast to remain a tropical storm after crossing the island of Hispaniola, which is shared by the Dominican Republic and Haiti, and then passing over Cuba into the Florida Straits.

According to the National Hurricane Center in Miami, at 8:00 am EDT on Friday, the centre of Tropical Storm Isaac was located about 175 miles south-southwest of Santo Domingo, Dominican Republic, and about 220 miles southeast of Port Au Prince, Haiti, moving toward the west near 15 mph.

A turn toward the west-northwest is expected later Friday, followed by a turn toward the northwest on Friday night. On the forecast track, the centre of Isaac will move near or over Hispaniola on Friday and move near or over southeastern Cuba on Saturday.

Reports from the hurricane hunter aircraft indicate that maximum sustained winds have increased to near 50 mph, with higher gusts. Additional strengthening is forecast while the centre remains over water. Tropical storm force winds extend outward up to 185 miles from the centre.

Total rainfall accumulations of 8 to 12 inches, with maximum amounts of 20 inches, are possible over Hispaniola. These rains could cause life-threatening flash floods and mud slides. Total rain accumulations of 4 to 8 inches, with maximum amounts of 12 inches, are possible across eastern Cuba and Jamaica. Total rain accumulations of 2 to 4 inches, with maximum amounts of 6 inches, are expected over Puerto Rico and the Virgin Islands. Total rain accumulations of 2 to 4 inches are possible over the southeastern Bahamas.

Tropical storm conditions were expected over portions of the Dominican Republic and Haiti on Friday. Tropical storm conditions are expected over the southeastern Bahamas and the Turks and Caicos Islands later Friday and Friday night. Tropical storm conditions are expected over eastern Cuba by Friday night. Tropical storm conditions are possible over central Cuba, the central Bahamas and Andros island by Saturday.

A storm surge will raise water levels by as much as 1 to 3 feet above normal tide levels in areas of onshore winds in the tropical storm warning area. Near the coast, the surge will be accompanied by dangerous waves.

Dangerous surf and rip current conditions will affect the Leeward Islands, Virgin Islands, Puerto Rico, Hispaniola, the southeastern Bahamas, the Turks and Caicos and eastern Cuba during the next couple of days.

Meanwhile, Tropical Storm Joyce has weakened to a weak tropical depression and at 5:00 am EDT on Friday was located about 1,110 miles east of the Leeward Islands, moving toward the northwest near 14 mph. A motion in this direction at a faster forward speed is expected during the next two days. Little change in strength is forecast during the next 48 hours.

The broad area of low pressure just to the south of the Cape Verde Islands is now given a medium chance — 30 percent — of becoming a tropical cyclone during the next 48 hours. Some development of this low is possible over the next couple of days as it moves toward the west or west-northwest at 10 to 15 mph.
