The Saturday morning webinar graphics have been updated for the new track information. Note that the latest forecast now shows Isaac becoming a category 2 prior to landfall in the Florida Panhandle.
Summary points from webinar:
***Tropical Storm Isaac has become better organized overnight. While it is still a tropical storm, the structure of the storm has improved.
***The threat of impacts are steadily increasing to the Florida Panhandle or Big Bend Region as well as further inland areas of Southeast Alabama and Southwestern Georgia.
***The intensity forecast is still uncertain. Less land interaction with Cuba could yield a stronger hurricane in the Gulf of Mexico.
***At this time, our most confident and primary concern is heavy rainfall
***Folks need to start thinking about wind and surge impacts.
***Forward motion at time of landfall is 10 mph. This equates to a widespread rainfall total of 10 to 15 inches with isolated higher totals in excess of 20 inches possible.
***Coastal counties need to be looking at Category 2 MEOW's for storm surge VERY PRELIMINARY!!!
***Probabilistic Surge is now available showing STORM TIDE (above ground level) VERY PRELIMINARY!!!
Florida Panhandle Counties (Walton, Bay, Gulf) range from 3 to 6 feet
Franklin County ranges 6 to 9 feet
Wakulla/ Jefferson range 6 to 10 feet
