EMSA issues a medical heat alert when it responds to five or more suspected heat-related illness calls in a 24-hour period. This is the fourth day in a row EMSA has issued a medical heat alert.
EMSA is urging citizens to take proactive measures to stay safe in the heat by keeping fluids accessible and drinking plenty of water before going outdoors and during outdoor time. It also asks you limit outdoor time and take frequent breaks in shade or indoors.
