...TROPICAL STORM GASTON...

TROPICAL STORM GASTON IS PRODUCING TROPICAL STORM FORCE WINDS OVER THE WESTERN AZORES. THE STORM WILL CONTINUE TO MOVE WESTWARD AWAY FROM THE ISLANDS AND IMPACTS WILL DIMINISH. GASTON WILL BECOME EXTRATROPICAL OVERNIGHT AS IT MOVES WESTWARD.

...TROPICAL DEPRESSION HERMINE...

TROPICAL DEPRESSION HERMINE IS BARELY HOLDING ONTO TROPICAL CHARACTERISTICS AND WILL LIKELY BECOME EXTRATROPICAL THIS EVENING OR OVERNIGHT. NO LAND IMPACTS ARE EXPECTED

...TROPICAL STORM IAN...

NOAA HURRICANE HUNTER HAS BEEN INVESTIGATING TROPICAL STORM IAN AND HAS FOUND THAT THE STORM IS STILL WORKING ON BECOMING BETTER ORGANIZED. IAN HAS BEEN SUFFERING FROM SHEAR WHICH IS FORECAST TO DECREASE OVERNIGHT. RAPID INTENSIFICATION IS POSSIBLE ONCE IAN FINISHES ESTABLISHING ITS INNER CORE. 

COMPUTER MODELS ARE STILL STRUGGLING TO GET A HANDLE ON THE LONG TERM FORECAST WITH IAN HOWEVER THE GENERAL UNDERSTANDING IS THAT IAN WILL TURN TOWARD THE NORTH LATER THIS WEEKEND AND HEAD INTO THE SOUTHEAST GULF OF MEXICO. 

ALL INTERESTS FROM SOUTHEAST LOUISIANA TO FLORIDA NEEDS TO MONITOR THE PROGRESS OF IAN AS ALL COMPUTER MODELS SHOW A VERY STRONG HURRICANE IN THE GULF BY EARLY NEXT WEEK.
