Residents across Maryland should prepare for severe weather, including heavy rain, frequent lightning, and strong winds. The primary risks include localized flooding, especially in areas under the Flood Watch, and potential tornadoes in regions under the Tornado Watch. Gusty winds could cause damage to trees and power lines, while heavy rain may lead to hazardous driving conditions. Even non-severe storms are expected to produce significant lightning and rainfall, posing risks to outdoor activities and evening plans.
