It's not uncommon for the state of Maryland to experience severe thunderstorms during the summer season. Thunderstorms are more likely to happen in the spring and summer months during the afternoon and evening hours, but can also occur year-round and at all hours.
Thunderstorms affect relatively smaller areas when compared with hurricanes and winter storms. However, all thunderstorms are dangerous. Every thunderstorm produces lightning, which kills more people each year than tornadoes. Heavy rainstorms can also accompany thunderstorms, and leads to problems such as flash flooding, strong winds, hail, and tornadoes.
