Miami, Fla. – After great Gulf Coast beach and boating weather during the Labor Day weekend, mercifully absent of any peak-season Atlantic tropical cyclone activity, the National Hurricane Center now has eyes on a new tropical wave in the eastern Caribbean. Five-day probability for tropical development is placed at 50 percent right now.

A second system in the western Caribbean is crossing the Yucatan and rated now at 20 percent likelihood for development during the next five days.

Labor Day 1935 brought the strongest hurricane ever recorded to make landfall in the U.S.

With winds of 185 mph and a 20-foot storm surge, the 'Labor Day' hurricane devastated Key West and the Florida Keys, claiming more than 400 lives. More than 200 of those killed in the storm were WWI veterans encamped at Key West while working on the new 'Overseas Highway' work project. It was of course the peak of the US Depression at the time.

Here's the 8:00 a.m. NHC update for Labor Day

 1. DISORGANIZED CLOUDINESS AND SHOWERS IN ASSOCIATION WITH AN ELONGATED AREA OF LOW PRESSURE EXTEND FROM THE EASTERN CARIBBEAN SEA ACROSS  THE LESSER ANTILLES AND INTO THE TROPICAL ATLANTIC. ALTHOUGH UPPER-LEVEL WINDS ARE FAVORABLE...THE PROXIMITY TO DRY AIR IN THE MIDDLE LEVELS OF THE ATMOSPHERE IS INHIBITING DEVELOPMENT OF THIS DISTURBANCE. THIS SYSTEM HAS A LOW CHANCE...20 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS...AND A MEDIUM CHANCE...50 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 5 DAYS WHILE IT MOVES WESTWARD TO WEST-NORTHWESTWARD AT AROUND 10 MPH OVER THE CARIBBEAN SEA...AND NEAR OR OVER HISPANIOLA. REGARDLESS OF WHETHER OR NOT A TROPICAL CYCLONE FORMS...BRIEF PERIODS OF LOCALLY HEAVY RAINFALL AND GUSTY WINDS ARE EXPECTED TO AFFECT PORTIONS OF THE LESSER ANTILLES OVER THE NEXT DAY OR SO.  OTHER SYSTEMS WITH FORMATION POTENTIAL BEYOND 48 HOURS...  A TROPICAL WAVE LOCATED OVER THE NORTHWESTERN CARIBBEAN SEA IS MOVING WEST-NORTHWESTWARD AT ABOUT 10 MPH. THIS SYSTEM IS EXPECTED TO MOVE ACROSS THE YUCATAN PENINSULA TODAY AND INTO THE BAY OF CAMPECHE TUESDAY THROUGH THURSDAY...WHERE SOME DEVELOPMENT IS POSSIBLE LATER IN THE WEEK. THIS SYSTEM HAS A LOW CHANCE...NEAR 0 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS...AND A LOW CHANCE...20 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 5 DAYS.  FIVE-DAY FORMATION PROBABILITIES ARE EXPERIMENTAL IN 2013.
