A clogged storm drain flooded a neighborhood near Boise State University Thursday, but other areas bore the brunt of the day's stormy weather, the National Weather Service reports.
Thunderstorms dumped about a half an inch of rain — and dime-sized hail — in about a half hour in Canyon County near Lake Lowell about 4 p.m., NWS meteorologist Megan Thimmesch said.
Varying amounts of rain and hail fell across the Valley, she said, but areas around Boise State and the airport saw relatively little precipitation Thursday.
The week's rainy weather likely had a cumulative effect on the storm drain on Longmont Avenue, south of the Boise River and a block east of Broadway Avenue, that backed up Thursday afternoon, Thimmesch said.
The roadway, a bank parking lot and nearby lawns were underwater, and that section of Longmont was closed for about 20 minutes while ACHD cleared the drain, Boise police report. Officers responded to the flooding report at 2:14 p.m.
Scattered rainshowers and isolated thunderstorms are expected Friday, especially in the afternoon, and possibly Saturday, Thimmesch said, advising area residents to check the latest forecasts before venturing out for barbecues or other outdoor activities this holiday weekend.
