Limited overnight relief with low temperatures in the mid 60s to low 80s. Resultant widespread Major HeatRisk, with areas of Extreme HeatRisk. * WHERE...Marin Coastal Range, Sonoma Coastal Range, North Bay Interior Mountains, North Bay Interior Valleys, East Bay Interior Valleys, Santa Cruz Mountains, Santa Clara Valley, Eastern Santa Clara Hills, East Bay Hills, Southern Salinas Valley, Santa Lucia Mountains and Los Padres National Forest, and Mountains of San Benito and Interior Monterey. * WHEN...Until 11 PM PDT Wednesday. * IMPACTS...Most individuals will be at risk for heat-related illnesses without effective cooling or adequate hydration, especially with prolonged outdoor exposure. Without effective cooling and/or adequate hydration, heat-related illnesses including heat stroke will be a risk to everyone. Overnight lows will warm as well leading to poor relief from the heat specifically in elevated terrain and interior areas. * ADDITIONAL DETAILS...An exceptionally dangerous situation is expected to unfold during this potentially historic and deadly heat event. Several days of temperatures well above normal will lead to compounding effects among people and infrastructure, with the possibility of numerous heat related fatalities. It cannot be stressed enough that while one day at these temperatures may be manageable for some, an event of this scale, magnitude, and longevity will likely rival anything we`ve seen in the last 18 years. Heat is the number one weather related killer in the United States. By this weekend, it is VERY LIKELY that we add to that statistic if preparations are not taken seriously. PRECAUTIONARY/PREPAREDNESS ACTIONS... Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances. Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency!
