The National Weather Service has issued an excessive heat watch for much of the Bay Area including Sonoma Valley this Friday, July 12th through late Sunday, July 14th due to hot temperatures (90-100+ degrees) combined with low humidity during the day with limited overnight recovery. The hottest days are forecast to occur on Saturday and Sunday. Warm overnight lows are expected.

What is an “Excessive Heat Watch?” An Excessive Heat Watch means that:
• Hot conditions could cause life-threatening impacts, or major impacts, to commerce or travel.
• There is a high, to very high, risk for much of the population due to long duration heat with little to no overnight relief.
• Prepare for dangerous heat, limit outdoor activities.

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 heatstroke. 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! Call 9 1 1.
