Delmarva’s first official weekend of summer sets the stage for a dangerous heat wave expected to peak Monday and Tuesday. With inland highs approaching 100°F and heat indices reaching up to 110°F, residents are urged to take precautions. A Heat Advisory is in effect for parts of Delaware and Maryland. Though some relief may arrive later in the week, sweltering conditions will dominate much of the region through at least midweek.

Summer is starting with a sizzle across Delmarva as a multi-day heat wave builds in. Sunday kicks things off with sunshine, climbing temperatures, and rising humidity — a preview of the dangerous conditions expected Monday and Tuesday. A Heat Advisory is in effect for parts of Delaware and Maryland, where heat index values could soar between 105 and 110 degrees. Relief may not arrive until late in the week as high pressure weakens and storm chances increase.
