Photos and Update from Isaac's Path in Florida

Tropical Storm Isaac is expected to be at hurricane strength when it reaches the Florida Keys Sunday night, according to the National Hurricane Center's 11 p.m. advisory.

Florida Governor Rick Scott declared a state of emergency Saturday afternoon and GOP officials decided to delay the Republican National Convention according to a Huffington Post report.

Isaac brought maximum sustained winds of 60 mph late Saturday night. Officials said the storm was churning northwest at 17 mph and should pass just north of the central coast of Cuba on Sunday night.

Delegates are expected to attend a brief ceremonial session Monday afternoon, where RNC Chairman Reince Preibus will formally kick off the convention before recessing until Tuesday evening according to Fayetteville's WRAL news team on the ground in Tampa.

Media and convention delegates will spend the rest of Monday monitoring the storm before Ann Romney and New Jersey Gov. Chris Christie take the stage Tuesday night.

The National Weather Service cautioned against concentrating on Isaac's exact path: strong tropical storm-force winds now extend outward up to 205 miles from its center, so much of South Florida should see heavy rains and will likely experience flooding.
