Big Bear, CA, June 15, 2016 – High pressure aloft over northern Mexico will strengthen and expand to the north and west bringing a strong warming trend for Friday through Sunday with excessive heat likely by Sunday for inland areas and possibly near the coast. The heat wave could extend past Sunday and Monday into the middle of next week, but that is less certain.
The hot temperatures and the transition from below average to well above average high temperatures could cause heat stress or illness. The potential for heat illness will increase if this heat wave extends beyond Sunday and Monday into the middle of next week. This heat could be life-threatening to unprepared hikers, especially in the deserts.
Take precautions for yourself as well as your family and pets. Stay hydrated and avoid strenuous activity, especially during the hottest afternoon hours. Make sure your pets have plenty of cool water to drink and a place to get out of the sun.
