Tropical Storm Dennis

Dennis becomes a "minimal hurricane".

The National Hurricane Center is warning Tropical Storm Dennis could bring hurricane force winds to the US by this weekend. A forecaster at the center says Dennis is "a minimal hurricane right now," even though its 70-mile-per-hour winds are four miles-per-hour below official hurricane strength.

Forecasters say the powerful storm is about 180 miles from Haiti. They've issued a hurricane warning for part of Haiti and for Jamaica. The center is warning that Dennis could hit Jamaica with up to a foot of rain in spots, causing potentially deadly flash floods and mud slides. Jamaica's prime minister has rushed home from a Caribbean summit in St. Lucia a day early.

A hurricane watch is in effect for parts of Cuba and the Cayman Islands. Forecasters say the storm's path could take it near the Florida-Alabama border by this weekend.
