Portions of central and eastern Virginia were under a flood advisory Monday as residents and officials assessed damage from storms that moved through several counties in the Richmond area.

Hanover County authorities said severe thunderstorms that moved through the area Sunday cut a 4-mile swath of destruction, damaging homes, downing trees and power lines and making driving hazardous. Similar damage was reported in New Kent and King William counties.

The National Weather Service had issued tornado warnings in the area, but it was unclear whether the damage was caused by a tornado. Weather-service officials said crews would assess the damage Monday.

Forecasters say up to 6 inches of rain fell in some parts of the Richmond area Sunday, where state police responded to 31 crashes. Police said most were weather-related, with drivers hydroplaning and striking trees or guardrails or overturning.
