LEONARDTOWN, MD – St. Mary’s County Government’s Department of Emergency Services (DES) urges community members to be prepared for severe storms that will impact our area beginning this afternoon, Monday, March 16, 2026. While rain and thunderstorms may occur throughout the morning and early afternoon hours, the most severe weather is anticipated between 3 – 7 p.m. for our area. A powerful cold front will bring a squall line into the area, bringing damaging wind gusts and large hail with the possibility of tornados. Wind gusts may be as high as 70 – 80 mph. This brings the potential to cause significant tree and power line damage, which could lead to extended power outages. It is important to know the difference between a Tornado Watch and a Tornado Warning: • Tornado Watch: Conditions are favorable for the development of a tornado in the area. Essentially this means a tornado could happen soon. • Tornado Warning: A tornado has actually been sighted by spotters or indicated on radar and is occurring in the warning area. This means a tornado is happening. Severe Storm & Tornado Preparedness • If a Tornado Warning is issued for your area: o Move to the lowest level of your home. o Move to an interior room without windows, like a closet or a bathroom. o If you have a basement, this is the best option. o Cover your head and neck to protect yourself from falling debris. • When thunder roars, go indoors! Always remember that if you can hear thunder, it is possible to be struck by lightning. • Be prepared for severe weather and always plan for the worst scenario. o Secure or bring indoors all outdoor toys, furniture, and items that could be moved by heavy winds; de-clutter drains and gutters; and consider hurricane shutters. o Have emergency supplies nearby such as flashlights, water, and portable chargers. o Check on your neighbors, friends, and family members, especially if they are elderly and/or have functional needs. o Bring your pets indoors during severe weather.
Know where the main valves and switches are for gas, water, and electricity – and ensure someone you trust can operate them in case you need to shut them off. o Follow the instructions of local emergency management officials. Knowing what to do before, during, and after an emergency is a critical part of being prepared and may make all the difference when seconds count.
