Extended Period of Bad Weather in Florida Begins

By: Bryan Norcross , 11:44 AM GMT on August 25, 2012

Not unexpectedly, Isaac seems to be surviving its trek across Haiti with it's circulation intact. In moved just far enough west for its core to miss the highest mountains, although the Hispaniola and Cuban land masses will have some tempering effect for the next day or so. The upshot is... the Florida Keys need to get ready for hurricane conditions immediately, including 1 to 3 feet of storm surge flooding at high tides. The worst of this flooding will not occur until Monday when the storm has past and the backside winds push the water into Florida Bay.

For Miami and the entire metro area, be ready for an extended period of very bad weather with winds gusting to hurricane force... likely through Monday. Some flooding around Biscayne Bay is expected at high tide.

The bad weather has already begun in South Florida due to an upper-level feature that is helping pull Isaac north. Well more that a FOOT OF RAIN may fall between today's rain and that directly related to Isaac.

Be prepared to stay indoors in a safe building through Monday. When the wind starts blowing in earnest, stay away from windows.

More on farther up the west coast later.

See you on The Weather Channel.

So happy to see you here with all us weather geeks! We value your input.

I think Isaac held together very well crossing Haiti and does not look like it is going to go across very much of Eastern Cuba.

I guess we will see.

Hope you give us your thoughts on the 11am update.

I am in Broward for the past 33 years...

Living in Broward County for Andrew, I appreciate everything you did then, I am now in Charlotte County and just missed any serious damage from Charley.
I am now watching and waiting trying to decide on putting up the hurricane shutters.
Any thoughts ?

Thank you, Mr Norcross...glad to see you blogging on WU. Thanks for stressing that this will be a wide spread and long duration event and that flooding and storm surge are a big danger. It's important that folks new to coastal areas realize this.

Thank you, Mr. Norcross, but on satellite, Isaac sure looks like a mess! That upper air feature you mentioned looks pretty strong. A one/two punch for florida .
