CENTER OF THE EYE OF HURRICANE FLORENCE MAKES LANDFALL NEAR WRIGHTSVILLE BEACH NORTH CAROLINA…

CAUSING LIFE-THREATENING STORM SURGES AND HURRICANE-FORCE WINDS… …CATASTROPHIC FRESHWATER FLOODING EXPECTED OVER PORTIONS OF NORTH AND SOUTH CAROLINA, CAT 1. But impacts more like a Cat 2 or 3 as explained in prior blog post.

Wind gusts of 105 mph at Wilmington NC the second strongest on record.

Water rescues underway or planned when conditions allow for the bright people who chose to ignore warnings in parts of Coastal NC with wind gusts to 115 mph and up to 10 foot storm surge along with battering waves and torrential rain. Structural damage to homes being reported. As the eye of the storm goes ashore in Southern North Carolina it just crawls West into South Carolina weakening to a Tropical Storm. So tropical storm conditions will continue to lash parts of NC/SC another 24-48 hours.

Negative impacts for GA will be restricted to Easternmost Georgia from Savannah to the Northeast Mountains.

Wonder where we get the data for above forecasts? It’s from SLOSH:

The Sea, Lake and Overland Surges from Hurricanes (SLOSH) model is a computerized numerical model developed by the National Weather Service (NWS) to estimate storm surge heights resulting from historical, hypothetical, or predicted hurricanes by taking into account the atmospheric pressure, size, forward speed, and track data. These parameters are used to create a model of the wind field which drives the storm surge.

The SLOSH model consists of a set of physics equations which are applied to a specific locale’s shoreline, incorporating the unique bay and river configurations, water depths, bridges, roads, levees and other physical features.

Likely be the heaviest rainfall in history for the Carolinas, surpassing Floyd and Jerry.
