Summary points from webinar:
***Tropical Storm Isaac is moving along the north coast of Cuba.
***Model guidance is becoming more variable...implying a lower confidence forecast
***Even with the uncertainty, the threat of at least some 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 8 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 1 MEOW's for storm surge VERY PRELIMINARY!!!
***Probabilistic Surge is now available showing STORM TIDE (above ground level)
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
Taylor/Dixie range 5 to 9 feet
***The next webinar is scheduled for 230 pm ET (130 pm CT) Saturday afternoon.
