Danse avec les cyclones ! image satellite du 12 08 2011

Mais le NHC indique à cette heure (10 heures GMT) : There are no tropical cyclones at this time.

1. AN AREA OF LOW PRESSURE CENTERED ABOUT 1175 MILES EAST OF THE
NORTHERN LEEWARD ISLANDS IS MOVING WEST-NORTHWESTWARD AT NEAR 20 MPH. SHOWERS AND THUNDERSTORMS HAVE BECOME A LITTLE BETTER
ORGANIZED...AND ENVIRONMENTAL CONDITIONS ARE GRADUALLY BECOMING
MORE CONDUCIVE FOR DEVELOPMENT.  THIS SYSTEM HAS A MEDIUM
CHANCE...40 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS.

2. A BROAD LOW PRESSURE SYSTEM LOCATED ABOUT 450 MILES SOUTHWEST OF THE SOUTHERN CAPE VERDE ISLANDS IS PRODUCING A LARGE AREA OF CLOUDINESS AND SCATTERED SHOWERS.  ENVIRONMENTAL CONDITIONS ARE EXPECTED TO GRADUALLY BECOME MORE CONDUCIVE FOR DEVELOPMENT OVER THE NEXT SEVERAL DAYS AS IT MOVES WESTWARD AT 15 TO 20 MPH.  THIS SYSTEM HAS A MEDIUM CHANCE...40 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.
