[9-26 PTC 9] - NHC is now issuing products on Potential Tropical Cyclone 9. This is formerly Invest 94L. Another note, movements and developments of PTC Nine through the next 12-24 hours will play a role on the forecast. This is a hype-free zone and what I say is based on NHC forecasting and my explanations as a meteorologist.
These products provide us a forecast cone and also an idea of how strong nine's future is. Nine is forecasted to become a hurricane and will be in proximity to the Florida East Coast. While the cone currently includes portions areas of NE Florida, I am anticipating some coastal impacts in the form of minor storm surge especially along the St. Johns River basin, high surf along the Atlantic, and some occasional strong gusty winds with periods of rain along the East Coast. Just because you're not in the cone does not mean you don't see impacts. Again, some coastal impacts are possible by the late weekend.
The forecast can STILL change, especially with what the system does through the next 12-24 hours. The spread in computer models in the short-term is not ideal but further serves my point in why the short-term movements matter. The locations of the upper-level pressure systems and even Humberto will also play a role in this system's future. Again, it's a complex and tricky forecast that continues to be worked out. While the threat for a Southeastern U.S. landfall (Carolinas area) is increasing, it is not set in stone.
For instance, if PTC Nine ends up being somewhat slower than forecast, Hurricane Humberto's influence could cause a change in forecast path. If the forward speed of PTC Nine is faster, then a landfall appears more likely. Again, showing how difficult the forecast is even in the short-term.
Hurricane Hunters are flying out to PTC Nine and Humberto to improve the forecasts. Again, I'm taking this day-by-day given the forecast is still somewhat complex and things can change these next few days. I'll have another post tomorrow.
