Tropical Storm Karen Aims For Gulf Coast

image

 

# 7832

 

 

It’s been an unusually quiet tropical season, but this morning the NHC upgraded an area of disturbed weather in the Caribbean to tropical storm status, and expects it to move towards the northern Gulf coast over the next 72 hours.

 

While unlikely to be a strong hurricane, weak hurricanes and  tropical storms can prove formidable depending upon their speed, rainfall rates, and the geography of the coast where they come ashore.  In addition to potential flooding, and high winds, small twisters are often reported with landfalling tropical systems.

 

If you live anywhere on the Gulf Coast, from Texas to Florida, today would be a good day to review your hurricane plans, and to make any last minute preparations.  If you haven’t already downloaded the Tropical Cyclone Preparedness Guide, now would be an excellent time to do so. It is a short (12-page), easy to follow guide that will walk you through the basics of understanding (and surviving) hurricanes and tropical storms.
