Governor Moore Declares State of Preparedness to Enhance Government Coordination Amid Extreme Heat Forecast

Published: 6/23/2025

ANNAPOLIS, MD — Governor Wes Moore this morning signed a State of Preparedness declaration ahead of a potentially hazardous heat wave with dangerously high temperatures for much of Maryland. According to the National Weather Service, extreme heat is expected Monday through Thursday, with increasing humidity during that time, requiring heightened awareness and preparedness from Marylanders and those visiting our state.

“Our top priority is the health and safety of Marylanders,” said Gov Moore. “This State of Preparedness will ensure that Maryland is coordinated and poised to protect our people in anticipation of extreme heat and humidity. We ask that all Marylanders do their part to stay vigilant, stay hydrated, and stay in cool locations as much as possible. Check on vulnerable family members and friends throughout the week to make sure they’re staying safe too.” 

State of Preparedness enhances the state's ability to respond swiftly and effectively to potential hazards and threats in advance of an actual disaster. The order directs the Department of Emergency Management to coordinate the comprehensive preparation of state government ahead of potential impacts from hazards or threats, providing a vital layer of protection for Marylanders without necessitating a State of Emergency.

According to the National Weather Service, Marylanders can expect the following conditions from Monday through Thursday:

  • Daytime temperatures in the mid-90s are expected for much of the state with highs possibly reaching 100 or more; heat indices are forecasted for 105-110 and a potential peak of 115.
  • Overnight temperatures are expected to remain above 80 degrees across most of Maryland.
  • Prolonged heat and humidity will increase the potential for heat-related illnesses, particularly for those working outdoors or participating in outdoor activities.
Preparedness Recommendations:

  • Never leave infants, children or pets inside a parked vehicle.
  • Increase fluid intake, regardless of activity level. Don’t wait until thirsty to drink fluids; drink more liquid than thirst indicates.
  • Avoid "heat hangover;" continue to drink fluids even after strenuous activity, enabling the body to maintain optimum hydration and helping prevent the after effects of heat exposure such as headaches and fatigue.
  • Avoid beverages containing alcohol, caffeine, or large amounts of sugar as they dehydrate the body.
  • Avoid very cold beverages as they may cause stomach cramps.
  • Limit exercise or outdoor activity between the hours of 11 a.m. and 3 p.m. when the sun is at its peak intensity. If active during this time frame, drink a minimum of 16 to 32 ounces of water each hour. 
  • Some medications, both prescription and over-the-counter, may increase the risk of heat related illness. Consult your physician if you have questions.
  • Wear sunscreen with a minimum SPF 15. Apply at least 30 minutes before going outdoors, and re-apply as necessary.
  • Rest frequently in shady areas so that the body’s temperature has a chance to recover.
  • If unaccustomed to working or exercising in a hot environment, gradually increase the pace and limit exercise or work time.
  • Wear lightweight, loose-fitting clothing; sunglasses to protect the eyes; and a wide-brimmed hat to provide shade and keep the head cool.
  • Know where your local cooling centers are located.
“Many Marylanders are at risk for heat-related illness during extreme heat like we are experiencing this week,” said Maryland Department of Health Secretary Dr. Meena Seshamani. “Remember to check on those who are particularly vulnerable to this weather — including young children, senior citizens, and people with chronic diseases. Be sure that they have the resources they need to stay comfortable and safe, or help them locate one of the dozens of local cooling centers available.”
