Weather service warns Mainers of thunderstorms, flooding and heat
Severe Thunderstorms Sweep Across Maine, Prompting Widespread Weather Advisories
PORTLAND, Maine — A turbulent mix of severe thunderstorms, dangerous heat, and the threat of flash flooding descended on Maine on Friday, with the National Weather Service issuing a flurry of advisories affecting nearly every region of the state.
The day’s most immediate concern came early in the afternoon when the weather service reported a severe thunderstorm near Norridgewock around 2:15 p.m. Moving east at roughly 10 mph, the storm had the potential to unleash wind gusts reaching 60 mph along with penny-sized hail, threatening damage to roofs, siding, and trees across parts of Kennebec, Somerset, and Franklin counties. That advisory has since expired.
Flooding posed perhaps the broadest danger. Much of western Maine found itself under a flood watch stretching into late Friday night, with forecasters warning that slow-moving storms could dump more than three inches of torrential rain within just an hour or two. The watch covered Franklin and Oxford counties, interior Cumberland and York counties, and southern and central Somerset County. The weather service cautioned that recent rainfall had already pushed rivers and streams to elevated levels, raising the risk that any additional downpour could trigger rapid, dangerous rises in waterways.
Northern and eastern portions of the state faced similar threats. The weather service office in Caribou placed much of northwestern Maine under a flood watch lasting until 3 a.m. Saturday. Piscataquis and Aroostook counties were placed under a separate flood advisory Friday afternoon into the evening, with minor flooding anticipated in low-lying areas. Forecasters also advised residents of northern Piscataquis and Penobscot counties that thunderstorms could push into the region late Friday afternoon and into the evening hours.
While storms and floodwaters threatened inland communities, much of interior southern Maine and neighboring New Hampshire grappled with the opposite problem: oppressive heat. A heat advisory remained in effect until about 8 p.m. Friday, with heat index values forecast to climb as high as 97 degrees.
Maine’s coastline was largely spared from the thunderstorm and flood warnings, but beachgoers and boaters faced their own concerns. The entire coast was placed under a beach hazard advisory, with the weather service warning that ocean water temperatures in the low 50s could lead to rapid-onset hypothermia, particularly given how much cooler the water would feel against the warm summer air.
Relief is on the horizon, however. The weather service office in Gray reported that a cold front was expected to cross the area Friday night, ushering in less humid conditions by Saturday. A broader break from the heat is anticipated through the weekend and into early next week.
Residents are encouraged to monitor local forecasts, avoid travel through flooded roadways, and take precautions against both heat-related illness and the risks posed by sudden severe weather.
