With Hurricane Bill expected to pass along the Atlantic coast this weekend, the Coast Guard is stressing the importance of safety for boaters and swimmers during the hurricane season. Hurricanes can create dangers in the water, such as rip currents and large waves. Rip currents and undertows can drag swimmers away from their boat or the beach and lead to death by drowning when they attempt to fight the current and become exhausted. According to the United States Lifesaving Association, rip currents cause approximately 100 deaths annually in the United States - more than all other natural hazards except heat and floods. More than 80 percent of rescues by beach lifeguards are due to rip currents, totaling 18,000 lifeguard rescues a year.
