What is in the statement?

The statement gives the following details:

This Hazardous Weather Outlook is for portions of North and Central Georgia.

.DAY ONE…Today and Tonight…

tonight with periods of heavy rain beginning this evening. The

increased risk of flooding begins tonight across North and

lower amounts in the 1 to 3 inch range expected over central

What is meant by “isolated” and “scattered”?

The NWS defines “isolated” as follows:

A National Weather Service convective precipitation descriptor for a 10 percent chance of measurable precipitation (0.01 inch). Isolated is used interchangeably with few.

“Scattered” has the following definition:

When used to describe precipitation (for example: “scattered showers”) – Area coverage of convective weather affecting 30 percent to 50 percent of a forecast zone (s).

In other words isolated means a few showers, scattered means the showers are likely to cover 30 to 50 percent of the affected region.
