Nate is continuing to gradually strengthen and still have the potential to reach hurricane strength before it makes landfall late Saturday night or early Sunday morning.  With Nate’s rapidly movement rainfall amounts of 3 to 6 inches, with isolated amounts of up to 10 inches will be possible, so while flooding from rainfall may be limited, storm surge flooding however is likely as storm surge potential are as follows for the northern Gulf coast…

Indian Pass to Crystal River, Florida…1 to 3 ft

Winds will also gradually be on the increase tonight into Saturday with tropical storm force winds moving on the coast by Saturday afternoon and hurricane force winds will occur within a small area by Saturday night and continue into early Sunday morning.

As Nate moves further inland, heavy rainfall will be possible for portions of the Ohio and Tennessee Valleys, the Appalachians, the mid-Atlantic, and New England.  Rainfall amounts in these areas will be in the 3 to 5 inch range, with isolated amounts up to 6 or 7 inches.  Winds of up to tropical storm force will be possible as far north as the Tennessee Valley.

Impacts possible from Nate across the northern Gulf coast

Preparations across the northern Gulf coast should be completed by tonight, early Saturday morning at the latest as conditions will worsen throughout the day on Saturday.  Power outages will also be possible so be sure to have extra cash on hand as ATMs will not work if the power is out.  We will continue to have updates on Nate throughout the day on Saturday on the Equinox Weather Facebook page.
