Although hurricanes and nor’easters can cause significant damage in Milford and along Delaware’s shoreline, severe thunderstorms can be just as dangerous. Frequent occurrences in the spring and summer, thunderstorms can quickly intensify, producing damaging winds, flash flooding and even tornadoes which pose serious risks to the area.
Delaware’s geography plays a major role in how these storms develop and move. The Delmarva Peninsula often sits at the meeting point of warm, humid air coming in from the Atlantic Ocean and cooler, drier air that moves in from the west. When the air masses collide, thunderstorms develop. In addition, the Chesapeake Bay can add additional moisture and heat, which may strengthen a storm or, as is sometimes the case, break them up completely so they never reach Delmarva.
A thunderstorm can produce wind gusts over 60 miles per hour, heavy downpours, lightning, hail and tornadoes. In July 2021, a tornado spawned during a thunderstorm caused significant damage in several areas around Milford. The tornado was classified as an EF-1. In 2023, an EF-2 tornado cut a swath of destruction from Ellendale to Greenwood, killing one man.
Even without tornadoes, severe thunderstorms can cause widespread damage. Strong straight-line winds can knock out power, tear off shingles and bring down large tree limbs, often without warning. Because these storms can develop and move quickly, officials stress that warnings should never be ignored.
When a severe thunderstorm warning is issued, it means dangerous weather will occur. Waiting to see if conditions worsen could put you and your family in danger. Residents should move indoors immediately, stay away from windows and avoid using electrical appliances during lightning. In the Milford area, the National Weather Service often issues an alarm warning that a tornado is possible. If that happens, take shelter in a basement or interior room at the lowest level of the home. Try to place your family under a load-bearing wall if possible.
If thunderstorms are predicted, preparation can help prevent tragedy. Secure outdoor furniture, trim trees and keep emergency supplies such as flashlights, batteries and a weather radio readily available. Charging phones and having a plan for where to shelter are also important.
After the storm passes, it does not mean the danger is gone. Downed power lines, debris and flooded roadways are still possible. Avoid standing in water and report any major damage to local authorities.
Anyone who has lived on Delmarva for any period of time knows thunderstorms are a fact of life, but it is also important not to downplay their danger. Storms can strengthen quickly and without notice. Understanding how a storm forms and moves across the area can help you prepare for the worst, even if the worst does not happen.
