The extreme heat poses significant risks, particularly in the deserts, mountains, and inland valleys, where temperatures are expected to reach dangerous levels. Vulnerable populations, such as the elderly and those with pre-existing health conditions, are at higher risk of heat-related illnesses. Coastal areas face hazards from strong rip currents and elevated wave heights, which can be dangerous for swimmers and surfers regardless of experience. Flooding in low-lying coastal areas may disrupt transportation and access to beach facilities.
