Ensure all crew members are wearing USCG approved Type I life jackets and nonessential crew are below decks. Deploy jack lines and harnesses if available. Check life saving equipment, including batteries on handheld radios, for readiness. Frequent lightning is occurring with these storms. If caught on the open water stay below deck if possible, keep away from ungrounded metal objects.
