A slow-moving front stretching northeast-southwest to the Ohio and Mississippi valleys this week will unleash a widespread flash flood hazard, including for water-saturated Kentucky, which is recovering from historic and catastrophic floods that saw fewer than two years ago Weeks at least 37 people died, continued to recover .
Abundant amounts of moisture accumulating along the front will fuel the development of numerous showers and thunderstorms through midweek, increasing flash flood hazards, particularly in areas where the ground has already been saturated from heavy rain and flooding in recent weeks.
“With this slow motion, we’re just channeling all that moisture into one spot,” said FOX Weather meteorologist Britta Merwin. “Now that doesn’t mean it will rain consistently across the area, but if it does start raining, it threatens to rain heavily in a short period of time.”
On Monday morning, showers and gales led to torrential rain in northwestern Illinois, prompting the National Weather Service to issue flash flood warnings Some roads were expected to become impassable.
The eastern portions of the Ohio and Tennessee Valleys will be most sensitive to flash flooding over the next few days. This includes flood-stricken eastern Kentucky.
While a wide area from northern New England southwest to the middle Mississippi Valley is at risk of flash flooding Monday, the highest flood risk is expected Tuesday and Wednesday.
Areas most at risk from flash flooding Tuesday include eastern Kentucky and adjacent parts of northern Tennessee, southern Ohio and southwest West Virginia.
A further widespread 1 to 3 inches of rain is expected in most areas along the slow-moving front this week. Insulated pockets of 3 to 5 inches cannot be ruled out, particularly in the eastern portions of the Ohio and Tennessee Valleys.
“In the afternoon we can have thunderstorms that can easily produce 2 to 3 inches of rain per hour and that’s the reason for the flash flood concern and the potential is there for everyone so it really just means you have to be vigilant. ‘ said Mervin.
The rainfall will certainly be welcome news for the Northeast, where drought conditions have developed in recent weeks due to a lack of rain, but it will only add to flooding concerns in the already saturated areas of Kentucky and the Midwest.
