Tropical Wave Bears Watching in the Caribbean

A huge tropical wave is starting to develop south of Cuba, and hurricane center forecasters say the system has the potential to become a depression.

Forecasters at the National Hurricane Center in Miami said that the broad low pressure system centered about 130 miles south-southwest of Grand Cayman Island is showing signs of becoming better organized.

"Shower and thunderstorm activity has increased near the low-level center and upper-level winds are gradually becoming more favorable for development to occur," forecasters said in a statement Thursday.

An Air Force Reserve unit reconnaissance aircraft is investigating the system. This system has the potential to become a tropical depression later as it moves to the west-northwest or northwest at about 10 mph.

If it develops sustained winds of 39 mph or more, the system would be named Stan, the 18th tropical storm of the 2005 Atlantic season.
