The Coastal Flood Advisory poses a risk of flooding along the San Diego coastline during evening high tides. Residents in low-lying coastal areas should remain vigilant. Monsoon storms in the mountains and deserts may bring localized flooding, lightning, small hail, and strong winds. High temperatures and humidity could also pose health risks, particularly for vulnerable populations such as children, the elderly, and those with respiratory issues. Outdoor workers and pets are also at risk from excessive heat.
