48 hours later - Isaac turning away

As you can see by comparing this "cone of uncertainty" from my post just two days ago, Isaac is meandering west ("go West, young storm") and now projected to find landfall between Pensacola and New Orleans.

It had left Haiti and was headed to the somewhat lower mountain ranges in the SE provinces of Cuba.  It is still considered a Tropical Storm, however Key West is now under a Hurricane Emergency Warning which our Governor declared in order to tap federal relief funds.
Taller mountains and land mass help defeat formation of a TS into a true hurricane.  That requires wind speeds in excess of 74 miles per hour sustained.

Some of the more dramatic media outlets are allowing as how it 'could' reach Category One status after passing over Monroe County (the Florida Keys south of Miami).  Winds at 60 MPH, pressure at 1,000 millibars.  Millibar (not MiniBar as found in expensive hotels and cruise ships) readings drop as pressure rises, so a falling barometer reflects an increase in wind and rain.  The Weather Channel now expects Isaac to be a weak Category 1 hurricane, with a track well out to sea.  Sunday night into Monday and Tuesday expected to be the heaviest rain and flooding in Tampa.  Ought to keep those "Occupy" weenies and anarchists off the streets - see, a silver lining.
