Parts of the Matanuska Valley are likely to see a second round of thunderstorms Tuesday afternoon, one day after a sudden downpour caused flooding in Palmer, forecasters say.
Thunderstorm conditions will peak between 3 p.m. and 9 p.m. Tuesday, extending from the Valley southward along the front range of the Chugach Mountains, according to a special weather statement issued by the National Weather Service.
“These storms will produce frequent lightning, small hail, heavy rain, and gusty winds. The storms will be slow moving, with potential for half an inch or more of rain. Thus, localized urban street flooding is also possible," the statement said.
A sudden downpour of rain and pea-sized hail on Monday caused dramatic flooding in Palmer. Nearly half an inch of precipitation fell on the city in just an hour and a half, according to meteorologist Rebecca Anderson of the National Weather Service’s Anchorage forecasting office.
Palmer hasn’t seen that much precipitation in a single day in exactly nine years, Anderson said. Monday’s storm tied a nine-year record set June 3, 2010.
Palmer City Manager Nathan Wallace said he wasn’t aware of any significant damage to buildings in the beyond anecdotal reports of basement seepage.
Forecasters say Tuesday’s round of storms are likely to affect the same areas.
“It’s very, very similar to what we saw yesterday,” Anderson said.
