Later Friday evening and into Saturday morning, expect heavy rain from Tammy to impact the Leeward and northern Windward Islands. That heavy rain should spread to the British and U.S. Virgin Islands and Puerto Rico as early as Sunday.

The rain produced by Tammy might produce isolated flash and urban flooding. It’s also possible that isolated mudslides in higher terrain could occur as a result of the heavy rain.

When Tammy moves near or over the Leeward Islands, storm surge may produce coastal flooding. Large and dangerous waves will follow the surge near the coast.

Tammy is traveling west-northwest at around 7 mph with a westward motion to a northwest turn is expected by Friday night or Saturday.

Tammy has sustained maximum sustained winds near 75 mph and a Minimum Central Pressure of 991 millibars, as of 2 p.m.

There is also a disturbance in the Caribbean.

According to WINK News Meteorologist Zach Maloch, “An area of low pressure could form this weekend over the southwestern Caribbean Sea. Some slow development of this system will be possible before it moves inland over Central America by the early to middle portion of next week.”

Over the next seven days, there is a 20% chance of further development.

Both this development and Tropical Storm Tammy are not expected to affect Southwest Florida.

The Weather Authority will continue to update information about Tropical Storm Tammy as new developments become available.
