The 2024 forecast is calling for an “above-normal” hurricane season, which, unfortunately, doesn’t give us any specific intel about where they will make landfall.

As the Atlantic hurricane season begins on June 1, the National Hurricane Center has released the names for this season’s tropical storms, including Alberto, Beryl, Chris and Debby, just to name a few.

Hurricanes can bring many different types of weather with them as they make landfall. The strong winds are the first thing that comes to mind.

Fortunately, the highest winds are always associated with hurricanes near or over ocean waters. Once they move inland the winds begin to decrease as hurricanes lose the connection to warm ocean waters. This does not mean we can’t get strong winds in Virginia, just that the winds usually will be much weaker once it moves well inland.

Hurricane force winds are at least 75 mph. The strong winds can easily blow down trees and power lines and cause difficult driving conditions due to flying debris and the force of the winds. Hurricane Isabel produced 60-80 mph winds across our region in 2005. The tremendous number of trees and power poles knocked down was due in part to the winds, but also the rain-soaked ground.

The strong winds also play an important role in raising the level of coastal and tidal river waters, called storm surge. Fortunately, the Lake Anna area is far enough inland that storm surges can’t affect us.
Hurricanes can also bring tornado outbreaks. Virginia’s worst tornado outbreak was in Sep 2004 with the remnants of Hurricane Ivan.

The last and most threatening phenomena from hurricanes, tropical storms or weakening tropical systems are the heavy rains and ensuing floods/flash floods that follow. One to two feet of rain is not uncommon for our region. Especially since we live in an area where the Blue Ridge Mountains tend to increase rainfall amounts and magnify the runoff. The mountains act as a barrier to the moist circulation around a hurricane. Strong easterly or southeast winds blow into the mountain and the air is mechanically lifted. This supports increased lift and water vapor is condensed into rain rather quickly. Some of Virginia’s heaviest rains have come from the remnants of hurricanes.

In August 1969 the remnants of Hurricane Camille brought severe flooding to the Blue Ridge, south of Charlottesville. Up to 31 inches of rain fell in 12 hours with devastating results. The ensuing flash flood and mudslide is estimated to have killed 153 people (not all the bodies were found). Most died in Nelson County.

In June 1972 the remnants of Hurricane Agnes moved into Virginia and produced one to two feet of rain that turned rivers and streams into raging torrents. Lake Anna was near completion and the runoff was a major contributor to filling the lake well before it was supposed to be filled.

The state of Virginia has setup a web page with lots of other useful information relating to hurricanes. This can be seen at https://www.vaemergency.gov/threats/hurricanes.
