Region under flash flood watch; colder temps on the way

The National Weather Service in Honolulu issued a Flash Flood Warning for Puna on Sunday, as heavy rain continues over the district with radar-estimated rates of 2 to 3 inches per hour between Pahoa and Kalapana.

The area of the flood watch includes the following counties Alamance, Anson, Chatham, Cumberland, Durham, Edgecombe, Franklin, Granville, Halifax, Harnett, Hoke, Johnston, Lee, Montgomery, Moore, Nash, Orange, Person, Richmond, Sampson, Scotland, Vance, Wake, Warren, Wayne, and Wilson. The following counties are under a Flash Flood Warning until 12:45 a.m.: Chatham, Durham, Granville, Harnett, Lee, Moore, Orange and Wake.

The GRCA issued the watch through to Tuesday, April 17, and cites current forecasts of local rainfall totals expected to reach 90 millimeters in some areas along the Grand River.

"Small streams and creeks, low-lying and poor drainage areas, and urban areas may see flooding problems develop as soon as Monday morning." the watch said.

A secondary cold front moving through the state will eventually clear us out but rain showers will linger across parts of the region through early afternoon. Flood waters will also threaten some homes and businesses. That means there is the potential for flash flooding which can be life-threatening.

Thunderstorms are expected to arrive just before or during the Monday morning commute according to the NWS.
