The NHC has designated the disturbance in the Gulf as Potential Tropical Cyclone (PTC) Three. The NHC gives this label to storms that they expect to become a tropical cyclone (TC) soon but they haven't quite got there yet. This allows them to start rolling out their different products and watches/warnings a little earlier than if they waited until a tropical depression had formed. Anyhow, now that you know that, you can take a look at the forecast map along with the wind speed and surge forecast maps.
A tropical storm warning has been issued from Intracoastal City, LA to the AL/FL line. PTC 3 is expected to become a tropical depression tonight or early tomorrow with some slight strengthening to tropical or subtropical storm strength before making landfall in LA early Saturday. Heavy rain will be the biggest hazard. Three day rain totals through Sunday morning are shown below. Note that isolated areas may see significantly higher amounts and it is likely that rain will linger in some areas through the beginning of next week.
Along with heavy rain there will be an isolated tornado threat as well.
Unless there's a significant change to the forecast this will be my one and only email about this system.
Have a good Friday and a great weekend and stay safe.
Chris
