Miami weather says there are u/l lows in the west and in the north that are funneling dry air down into the storm from the NW.
Oh, and the traffic is terrible too. I called my boss (because I'm out on "sales calls" this afternoon), and asked him about tomorrow. Business as usual, come in in the morning. What!?!
Dry air is our ally........hope it does the job of keeping "Ernesto" weak as can be expected.
