Between four and six inches of rain is predicted, with isolated pockets of up to 10 inches of rain possible.

PANAMA CITY — With heavy rains predicted, a flash flood watch has been issued for much of Northwest Florida, including Bay County.

The National Weather Service of Tallahassee issued a flash flood watch starting at 7 p.m. CDT Tuesday night and lasting through Thursday evening. The warning covers Walton, Holmes, Jackson, Washington, Calhoun, Bay and Gulf Counties.

Between four and six inches of rain is predicted, with isolated pockets of up to 10 inches of rain possible.

"There's a lot of tropical moisture and a boundary stalling over Alabama," said National Weather Service Meterologist Jeanie McDermott.

While the tropical moisture is typical of summer time in Florida, McDermott said, the boundary that is holding the weather systems in place is not, creating the wetter than normal conditions.

The rainfall, she said, is likely to be heaviest near the coastline in Bay and Walton counties.

"With this system, the areas near the coast will be more prone (to heavy rain)," she said.  Adding, that the coastal communities "can take more as the water runs off and goes into the sand."

Areas with heavy rainfall in a short period of time are particularly vulnerable to flash flooding. McDermott said some localized flash flooding can probably be expected at "some point" during the watch.

The Weather Service cautions that flash flooding is “very dangerous.” People are advised to continue to monitor the forecast and should be prepared for a flash flood warning to be issued.
