Residents of Imperial County West and Imperial Valley are advised to take immediate precautions due to an Extreme Heat Warning issued by the National Weather Service Phoenix AZ. The warning is in effect from Thursday, October 7 at 11:52 PM MST until Friday, October 8 at 8:00 PM MST.

Dangerously hot conditions are expected, with afternoon temperatures ranging from 104 to 111 degrees. This level of heat poses a Major Heat Risk, significantly increasing the potential for heat-related illnesses such as heat cramps and heat exhaustion, which can escalate to heat stroke if not addressed.

The National Weather Service urges everyone to take extra precautions, especially those who work or spend time outdoors. Strenuous activities should be rescheduled to early morning or evening hours. It is crucial to recognize the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight, loose-fitting clothing and drink plenty of water.

For those working outdoors, the Occupational Safety and Health Administration recommends frequent rest breaks in shaded or air-conditioned environments. If someone is overcome by heat, move them to a cool, shaded location immediately. Heat stroke is a medical emergency – call 911.

Public cooling shelters may be available in some areas. Residents should consult county officials for more details on cooling center locations.
