The Atlantic Hurricane and Summer Storm Season officially began on June 1 and will run through Nov.

Montgomery County’s Office of Emergency Management and Homeland Security (OEMHS) joins the Maryland Emergency Management Agency and the National Weather Service (NWS) in urging community members to familiarize themselves with what to do before, during, and after a severe storm. While it is possible for a hurricane or tropical storm to impact Montgomery County, the greater summer weather threat include

  • flooding
  • hail
  • lightning strikes
  • thunderstorms
  • strong winds

Thunderstorms can occur singly, in clusters, or lines and typically produce heavy rain for a brief period. During severe thunderstorms there is a risk that a tornado could occur.

“During the summer months, it is important to know the difference between a weather watch and warning, and understand that when a warning is announced, it is important to take immediate action,” said OEMHS Director Earl Stoddard. “I encourage everyone to sign-up for Alert Montgomery to receive emergency updates to protect yourself and your loved ones.”
