New rain not expected to raise flood concerns

Despite the heavy rain late last week, and the high water remaining in some rivers and creeks across the region, forecasters don't expect new flood issues with the rain due overnight into Wednesday.

The National Weather Service is predicting a three-quarters to one inch of rain tonight and Wednesday morning. That would bring the month's total at BWI-Marshall Airport close to 4.5 inches, well over the 3.93-inch average for March, with two more weeks to go.

But, forecasters said, this amount of new precipitation, "over the course of about a 12-18-hour period is not expected to bring area rivers back to bankfull or minor flood stages."

Last week's rain topped 3 inches in many spots north of Baltimore. It brought minor flooding to the Monocacy, Potomac and Susquehanna Rivers in Maryland, and inundated numerous low spots around the region, closing roads and detouring traffic. Some business along the Jones Falls in Baltimore were evacuated.

The new rain is coming with a storm brewing Tuesday in the Tennessee Valley and moving in our direction. Increasing clouds will begin to drop light rain here by evening, and rain rates will increase overnight, forecasters said. It should end by noon in the Baltimore area.

Once the storm clears out, we can look forward to sunny skies through the weekend, with a high of 74 on Friday before another, dry, cold front passes by during the weekend and drops highs back to the 60s.
