UPDATE: 9:56 p.m.

Roanoke, VA - Heavy thunderstorms Wednesday dumped between three and six inches of rain right over Roanoke City just a few hours time, leading to more flash flooding.

The National Weather Service issued a Flash Flood WARNING for Roanoke through the evening.

Many roads in Roanoke are still reported underwater, and officials advise never to drive across a flooded roadway.

Roanoke Fire/EMS performed 21 swift water rescues between 3:30 p.m. and 5:44 p.m., officials said. Children from a Roanoke daycare were also rescued as the high water came up fast Wednesday afternoon.

There are still weaker showers and storms moving through parts of the viewing area Wednesday night. The latest radar shows the activity.

As a cold front nears the area Thursday, it will help generate more heavy rain and thunderstorms throughout the day. Torrential downpours of one to two inches of rain in an hour could cause flash flooding of streams and creeks into Thursday as well.

The National Weather Service has issued a Flash Flood Watch for the Roanoke Valley and the New River Valley through 2 a.m. Thursday for the possibility of high water concerns. Remember, the ground is already very soggy and simply can't hold additional water.

We are also watching the tropics. Although Tropical Storm Chantal may lost its identity Wednesday evening, we still need to track the moisture from the system into the weekend, especially if you have plans at the beach Saturday and Sunday.

You can track the tropics in the ABC 13 Weather Center's Hurricane Tracker.

The good news is Friday into the weekend look drier. For the latest on the forecast, head over to the ABC 13 Weather Center for the latest.
