Multiple Rounds of Heavy Rain Saturday afternoon through Monday night
The risk for flash flooding will grow over the weekend as a series of showers and thunderstorms develop along a stalled frontal boundary which will linger over the region into early next week. A moist airmass will support periods of torrential rain, heaviest in thunderstorms. After each round of rain the wet ground conditions will support more rapid runoff and increase the threat for flash flooding.
FLASH FLOOD WATCH IN EFFECT FROM SATURDAY AFTERNOON THROUGH LATE MONDAY NIGHT
The National Weather Service in Cleveland has issued a * Flash Flood Watch for portions of Ohio and northwest Pennsylvania, including the following areas, in Ohio, Ashland, Ashtabula Inland, Ashtabula Lakeshore, Crawford, Cuyahoga, Erie, Geauga, Hancock, Holmes, Huron, Knox, Lake, Lorain, Lucas, Mahoning, Marion, Medina, Morrow, Ottawa, Portage, Richland, Sandusky, Seneca, Stark, Summit, Trumbull, Wayne, Wood, and Wyandot. In northwest Pennsylvania, Crawford, Northern Erie, and Southern Erie.
From Saturday afternoon through late Monday night
Multiple rounds of heavy rain possible through late Monday night. Rainfall amounts of 2 to 3 inches with locally higher amounts up to 4 to 6 inches possible.
The risk for flash flooding will increase after each round of rainfall, particularly in poor drainage areas near creeks, streams and ditches. Street flooding is likely. Rapid runoff will cause area rivers and stream to rise, likely resulting in flooding.
A Flash Flood Watch is issued when there is a potential for flash flooding. Flash flooding is a very dangerous situation. Monitor the forecast and be prepared to take action should Flash Flood Warnings be issued or if flooding develops.
