Governor Wes Moore Declares State of Preparedness Ahead of Historic Heat Wave Expected Across Maryland

Governor Wes Moore has declared a State of Preparedness as Maryland braces for what officials describe as a historic heat wave expected to bring dangerous temperatures and extreme heat conditions across the state through the Independence Day holiday weekend.

According to the governor's office, the State of Preparedness will remain in effect as Maryland experiences prolonged periods of excessive heat from Wednesday, July 1, through Sunday, July 5. The most dangerous conditions are expected Thursday through Saturday, when daytime temperatures could climb into the upper 90s and exceed 100 degrees in some areas. Heat index values are forecast to range from 105 to 110 degrees, with some locations potentially reaching 115 degrees.

"The health and safety of Marylanders, and those visiting our state for this holiday week, is our top priority," Gov. Moore said in a statement. "This State of Preparedness will ensure that Maryland is ready to protect our people ahead of this extreme heat."

The declaration is intended to strengthen the state's readiness before conditions worsen. Unlike a State of Emergency, a State of Preparedness allows state agencies to coordinate resources and preparedness efforts in advance of potential impacts without activating emergency powers.

Russ Strickland said the Maryland Department of Emergency Management is coordinating statewide preparedness efforts, including information sharing among state, local, nonprofit and private-sector partners to ensure resources are positioned where they may be needed.

Forecasters also expect little overnight relief, with nighttime temperatures remaining above 80 degrees across much of Maryland. Officials warn that prolonged heat and humidity will significantly increase the risk of heat-related illnesses, particularly for people working outdoors, participating in outdoor activities, older adults, young children, individuals with chronic medical conditions and other vulnerable populations.

State officials are encouraging residents to take precautions throughout the heat wave, including:

Never leave children, infants or pets inside parked vehicles.

Drink plenty of water before feeling thirsty and continue hydrating after strenuous activity.

Avoid alcohol, caffeinated beverages and drinks high in sugar, which can contribute to dehydration.

Limit or reschedule outdoor activities during the hottest parts of the day whenever possible.

Wear lightweight, loose-fitting clothing, sunscreen, sunglasses and a wide-brimmed hat.

Take frequent breaks in shaded or air-conditioned locations.

Know the location of nearby cooling centers.

Be aware of Maryland's workplace heat regulations for employees working in hot conditions.

Officials continue to encourage Marylanders to monitor weather conditions throughout the holiday weekend, stay hydrated, look after family members and neighbors, and take precautions to reduce the risk of heat-related illness as extreme temperatures persist across the state.
