Catastrophic Hurricane Irma heading for Leeward Islands. Florida must get ready.

Category 5 Hurricane Irma bearing down on the Leeward Islands at 8:45 am CDT Tuesday.

If you’re in South Florida or the Florida Keys…you need to know what you’ll to once watches and warnings are issued BEFORE they are issued. I do have enough confidence in the path of Hurricane Irma to state that Florida is in a very serious situation based on forecast data and so folks need to 1) track the forecast 2) know your plan, especially if you live in coastal evacuation zones 3) have emergency supplies ready. This storm already has the potential to be devastating for many people all week as it buzzsaws its way through the northern Leeward Islands, close approach to US and British Virgin Islands, then the US territory of Puerto Rico with 3.5 million people, the Dominican Republic, then portions of the Bahamas, before a close passage of the coast of Cuba. And it could do this as a large Category 4-5 hurricane. 
Most likely time of arrival of tropical storm force winds overlay 7 am CDT probability of those winds during 5 day forecast period. Note South Florida is most likely to see winds arrive by Saturday morning and they could arrive overnight Fri-Sat, with the eye not expected near Florida until Sat night-Sun morning.

Get ready, be ready to act if/when watches/warnings are issued and keep track of the latest forecast. Also, hope the best for our friends facing Irma right now.

I’ll updates on Irma throughout the week and you can follow me on Facebook and Twitter.

EDIT AT 10:20 am CDT: Winds in Hurricane Irma increased to 180 mph, making it the most powerful hurricane (by wind) ever observed in the North Atlantic outside the Gulf of Mexico and Caribbean Sea.
