LANHAM, Md. (WNEW) — Strong storms with potentially damaging winds and torrential downpours battered the Baltimore-Washington region again Tuesday.
A Flash Flood Watch remains in effect until 10 p.m., when most of the rain is expected to exit the region.
The severe weather began blowing through the area during the early afternoon. A Tornado Warning was issued for central Anne Arundel County for nearly half an hour.
The heavy rains have flooded road and toppled trees and power lines around the region.

Storms that rolled through the area Monday brought heavy rain and damaging winds to the area. There was even a Tornado Warning in effect in Baltimore County for a short time.
Cooler temperatures are forecast Wednesday and Thursday as cooler air is expected to make its way down from the north.
Temperatures could drop as much as 10 degrees below average throughout the region. The average high temperature for July is 89 degrees.
Accuweather meteorologist Dave Samuhel says this round of unseasonable air from the north will make for pleasant conditions, unlike the “polar vortex” that crippled the region in January.
“We have a big change in the overall weather pattern, mostly being instigated by a change in the jet stream, and that jet stream will be diving unusually far south. This will be accompanied by a lot of cool air,” he said. “Overall, this massive cool air we have coming out of Canada will provide nice weather for us.”
However, the Midwest is expected to see the biggest drop in temperatures with highs only reaching the low-70s in Minneapolis and Detroit.
“It will bring some unusually cool air, but the height of this cool air will be across the Northern Plains, the Upper Midwest and into the Ohio Valley. Those places are looking at highs 20 below normal, so a big difference there,” Samuhel said. “They’re going to set record temperatures for cold high temperatures in those areas, but no records for us.”
The dip in temperatures would be a drastic change to the heat waves the region has already seen this summer.
The heat and humidity earlier this month combined to make the air feel as hot as 105 degrees while sweltering heat baked the mid-Atlantic, breaking the high temperature recorded on June 17 in Washington.
