Penny-sized hailstones cut a swath through the Camas Prairie and Clearwater River area Thursday afternoon and meteorologists warn there could be flooding today.
“We’ve had a pretty good thunderstorm south of Grangeville and it moved over the terrain and progressed toward Kamiah, Greer and Weippe,” said Corby Dickerson, a meteorologist with the National Weather Service in Missoula, Mont.
“We’ve gotten reports of winds gusting 40 miles an hour in Grangeville and hailstones about a quarter of an inch to a third of an inch in size.”
Dickerson said with the heavy rain expected overnight “what we’re concerned about most is the fact that we have a potential for additional storms and could get several successive storms over the same area. If we end up with multiple storms, it could produce overland flooding and flash flooding.”
The Lewiston-Clarkston Valley also experienced some rain cells and gusty winds, said Steve VanHorn, a meteorologist with the weather service in Spokane. But the more severe weather settled around the Kamiah-Greer area.
Idaho County is continuing to deal with roads and culverts that washed out during heavy rains in April, and so far little of that damage has been repaired.
Dickerson said with the continued rain through the end of the week, “there could become some issues as far as creeks and streams becoming a bit more swollen.”
As of 8 p.m. Thursday, the weather service reported that 0.61 inches of rain had fallen in the Grangeville area over about an hour period. That was the most rainfall measured in the area. The Lewiston-Clarkston Valley received 0.04 inch of rain; Anatone measured 0.10 inch; Craigmont had 0.10 inch; and Orofino had 0.25 inch of rain. No flooding had been reported, according to a spokesman at the Spokane office.
Showers were expected today and through the weekend, with highs in the 60s to the low 70s.
