Thunderstorm wind is the standout hazard at Petersburg National Battlefield, with 6 recorded events in Dinwiddie County leading all other incidents. These storms can drop fast-moving, damaging gusts across the open battlefield terrain with little natural shelter, and two flash flood events on record show that heavy rain can quickly make low-lying areas and unpaved roads dangerous as well.
When a storm rolls in, move away from the large open fields and isolated trees immediately and get into a hard-sided vehicle rather than a tent or picnic shelter. Pack a NOAA weather radio or download the NWS app before your visit, since cell coverage can be spotty in rural Dinwiddie County. If you're driving the tour road, avoid creek crossings and pull-offs in low areas during or after heavy rain, as runoff can pool faster than it appears on the map.

About Petersburg National Battlefield
Two hundred ninety-two days, eight offensives, over 70,000 casualties, U. S. Colored Troops, and the decline of Gen. Lee's Army of Northern Virginia all describe the Siege of Petersburg. U.S. forces cut off supplies to both Petersburg and the Confederate capital, Richmond. Today, the park preserves the sites of this pivotal campaign.
