The 2012 season is lagging behind past seasons: By Sept. 5, 2005, we had three major hurricanes (Dennis, Emily, and Katrina),and by Sept. 5, 2011, we had one major hurricane (Katia). This year, we have one-- Michael.
ISAAC: FROM TS ON AUG, 21 TO HURRICANE ON AUG. 26
ISAAC DID NOT RETURN IN THE GULF AS TS NADINE: SEPT 12
LESLIE: FROM A TS ON SEPT 3 TO HURRICANE ON SEPT 5
SEPT 8: CAT 1 HURRICANE LESLIE IS HEADED SLOWLY NORTHWARD TOWARDS BERMUDA AND CANADA
SEPT 9: LESLIE PASSES 120 MILES EAST OF BERMUDA
TROPICAL STORM MICHAEL: FAR OUT IN ATLANTICSEPT. 4
Between 5 a.m. on Wednesday and 5 a.m. Thursday, Michaels pressure suddenly fell 40 mb and the maximum sustained winds increased by 63 mph, truly a remarkable case of rapid intensification
TROPICAL STORM NADINE BECAME A CAT 1 HURRICANE ON SEPT. 14 th Because of its location in the Azores, Nadine, the 8 th hurricane of the season, did not cause any major concerns in spite of its unusually long life.
TROPICAL STORM OSCAR FORMED WEST OF THE CAPE VERDE ISLANDS ON OCT. 4 th Oscar, the 15 th storm of 2012, was not expected to last very long or to cause any major problems.
SANDY: OCTOBER 24 Sandy, now the seasons ninth hurricane, became a huge storm with wind and rain bands reaching out 500 km or more from the storm center, producing 15-50 cm of rain in Jamaica, Bermuda, Haiti, Dominican Republic, and Cuba
LIKELY IMPACTS OF SANDY ON FLORIDA SATURDAY-- OCTOBER 27 Miami, Florida, which is already water- logged from 1 ½ meters of rain this summer, is expected to experience more rain, gusty winds, huge waves, and dangerous rip tides as a likely weakened Sandy continues to move northward.
SANDY: RAIN BEGINS IN FT LAUDERDALE, FLORIDA; OCT. 26
POSSIBILITIES AFTER FLORIDA SATURDAY Sandy could veer northeastward and eventually die in the Atlantic, OR, MORE LIKELY … As Sandy moves northward, it could become a powerful SUPERSTORM causing losses of $ 1 billion dollars + bringing heavy rain, high winds, and power outages along Eastern seaboard
