Ida Remnants In MD Could Drop 6 Inches Of Rain, Spawn Tornadoes

MARYLAND — The remnants of what is now tropical storm Ida could bring up to 6 inches of rain to parts of Maryland Wednesday into Thursday. A flash flood watch is in effect for the Baltimore-Washington, D.C., region Wednesday and Thursday, with up to 6 inches of rain possible.

In addition to heavy rain, the storm could bring severe thunderstorms and flash flooding.

The region is also under a flash flood watch from 2 to 10 p.m. Monday with scattered showers and thunderstorms likely into the evening, some of which may produce a few inches of rain in a short period of time.

Hurricane Ida made landfall in Port Fourchon, Louisiana, Sunday morning as a Category 4 hurricane with winds of up to 150 miles per hour. The storm has since caused thousands of power outages in Louisiana and the flow of the Mississippi River to reverse, according to reports. More than 1 million are without power in the New Orleans area as the storm makes its way up the coast, according to The Weather Channel and others.

According to the National Weather Service, the storm's remnants will pass through Maryland on Wednesday, departing Thursday morning. The storm could bring tropical downpours and tornadoes as it moves through the region.

"The remnants of Ida will interact with a stalled front, resulting in a prolonged period of heavy rainfall beginning Wednesday morning and continuing through Wednesday night," the National Weather Service said. "Rainfall amounts of 2 to 4 inches are expected, with localized amounts up to 6 inches possible."

This amount of heavy rainfall will not only result in the potential for considerable flash flooding of creeks, small streams, and urban areas, but also the potential for river flooding, the agency said.

A hazardous weather outlook is posted for the Maryland portion of the Chesapeake Bay, Tidal Potomac River, and I-95 corridor through central Maryland, northern Virginia, the and District of Columbia.

The flash flood watch is in effect from 11 a.m. Wednesday through 8 a.m. Thursday, the weather service said. Heavy tropical rainfall could result in considerable flash flooding.

A few severe thunderstorms are possible Wednesday into Wednesday night. Damaging wind gusts and a brief tornado are the main threats, the weather service said.

Moderate tidal flooding is possible Wednesday into Wednesday night at sensitive low-lying coastal locations.

Maryland counties in the flash flood watch include: Carroll, Baltimore, Cecil, Prince George's, Anne Arundel, Montgomery, Howard, and Harford.

Cities in the watch area include Baltimore, Bowie, Annapolis, Odenton, Westminster, Silver Spring, Bethesda, College Park, Reisterstown, Columbia, Severna Park, Greenbelt, Germantown, Rockville, Jarrettsville, Frederick, Arnold, Suitland-Silver Hill, Gaithersburg, Severn, Eldersburg, Clinton, Glen Burnie, Ellicott City, Laurel, and Aberdeen.
