Severe weather: High winds, tornadoes possible
- High winds and heavy rains are expected this afternoon, the National Weather Service warns.
- Wind gusts could reach 60 miles per hour, tornadoes are possible, a State College meteorologist said.
- Heavy rains are capable of producing flash floods in low-lying areas. Have a plan and a way to receive updates.
UPDATE: A National Weather Service severe thunderstorm warning is now in effect until 4:45 p.m.
A sever thunderstorm watch remains in effect until 10 p.m. as storms with the potential for wind gusts of up to 60 miles per hour move through York County and the surrounding area Sunday afternoon, the National Weather Service at State College warns.
The possibility exists for some flooding as well as isolated tornadoes, meteorologist Elyse Hagner said.
"We're expecting the thunderstorms to develop during the afternoon hours. The biggest threat with that are possible wind gust from 30 to 60 miles per hour," she said. Heavy rains in isolated areas could produce some flooding, she added.
The severe weather, targeting the entire East Coast, is expected to begin early in the afternoon and will last into the evening. Carl Lindquist, York County communications director, said officials say they are "actively monitoring conditions and will communicate with municipalities as weather occurs.
"The initial response to any specific emergency is made by municipal response agencies. We stand ready to support the municipal response should the need arise," Lindquist said.
"We are also actively communicating with the public via our Emergency Management social media channels."
Yorkers with outdoor plans should make certain they have a way to receive weather information — such as a radio, or a smart phone with a weather app — in case severe weather watches or warnings are initiated. And they should have a place to go if conditions begin to deteriorate, Hagner said.
Cancellation: The third annual Kiwanis Lake Human Be-In, scheduled from 11 a.m. until 6 p.m. Sunday at Kiwanis Lake, along Parkway Boulevard in York City, has been cancelled.
The cause behind Sunday's expected rough weather are twofold. A warm front has been draped across the region for some time. A cold front coming through this afternoon will come into contact with the warm front to produce thunderstorms.
"That and, depending on how much sunshine we have today before the storms get here, that may further destabilize the atmosphere," Hagner said.
The forecast for the remainder of the week looks better, despite the afternoon storms expected Sunday. Yet the approaching cold front will not provide immediate relief from the recent high temperatures the area has been experiencing.
"You probably won't really start seeing the temperatures drop down until Tuesday, and even then the high Tuesday should be around 80," Hagner said. "By Wednesday you should see cooler temperatures, and Thursday as well, with highs around 70."
The relief will be short-lived, however, as higher temperatures will resume by the end of the week, Hagner said.
