cyclone Idalia approaches southeast Georgia. The heaviest rainfall

totals associated with this system will be across far

southeastern portions of the area where as much as 3 to 6 inches

of rainfall with locally higher amounts is possible which will

What is the difference between “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.
