Two rounds of thunderstorms are expected to pass through the coastal waters and bays. The first round is expected to arrive Friday morning and last through the day, with the second round expected to pass through Saturday afternoon into Sunday. These thunderstorms bring the risk of frequent lightning, locally gusty winds, localized heavy rainfall, accumulating small hail, and waterspouts. Mariners should note the expected forecast and have a plan to reach safe harbor quickly if thunderstorms develop.
