ALT Key Messages: 1. Nolo is expected to remain south of the Big Island of Hawaii through Saturday before turning westward and moving away from the island. Tropical storm conditions are expected to begin on the Big Island tonight with hurricane conditions possible on Saturday, particularly in areas of steep terrain. Residents should follow advice given by local officials, including evacuating if told to do so. 2. The time to finish preparations for significant heavy rain and flooding impacts on the Big Island is now as heavy rain increases in both coverage and intensity today. Periods of heavy rain are expected to continue across the Big Island and Maui through the weekend. Life-threatening, catastrophic flooding and mudslides are possible, especially in areas of steep terrain across the eastern and southern portions of the Big Island and Maui. Across the remainder of Hawaii, lesser rainfall totals are expected, with isolated flooding possible.

ALT Rip Currents: Know Your Options. Rip currents are powerful currents of water moving away from shore. They can sweep even the strongest swimmer away from shore. If at all possible, swim near a lifeguard. If caught in a rip current: 1) Relax, rip currents don't pull you under. 2) Don't swim against the current. 3) Swim out of the current, then to shore. 4) If you can't escape, float or tread water. 5) If you need help, yell or wave for assistance. The image shows a rip current as a narrow flow of water moving in a line directly away from the beach, with waves on either side moving in the opposite direction towards the beach. Arrows point away from either side of the current and into the waves, parallel to the beach, indicating the path of escape from the rip current.
