The next coastal storm I spoke of yesterday has developed faster than forecast yesterday, and originated close to FL. over the extreme NE GOMEX. This low is forecast to move and deepen quickly, and is slated to be off the OBX by sometime tonight, approximately 7:00 – 10:00 p.m. EST. As the coastal storm deepens, NE winds are forecast to increase to around 25 – 35 kts (30 – 40 mph), and 35 – 50 kts by tonight, with higher gusts. A storm warning is in effect for the area until tomorrow morning.
