Heat warning extended to Friday

An excessive heat warning has been extended to Friday at 11 a.m. and weather officials are urging Nevada County residents to stay indoors with air conditioning to escape it and persistent bad air quality.

The National Weather Service in Sacramento extended the warning this morning that was projected earlier this week to last into Thursday afternoon.

In addition, wildfires burning all over the north state continue to produce smoke that is dangerous if it can be seen or smelled.

Ozone conditions in Grass Valley were at the 100 points level from 7 p.m. to 11 p.m. Tuesday night.

That’s only one point below the 101-150 unhealthy for sensitive individuals range that triggers concern for the elderly, children, pregnant women, athletes and those with existing heart and lung conditions.

As temperatures climb near 100 degrees today through Friday’s heat warning deadline, ozone levels could creep up into the unhealthy for sensitive individuals range again, or even the unhealthy range for 151 to 200 points.

Residents are urged to drink plenty of water and non-alcoholic fluids by the National Weather Service. They are also urged to check on neighbors and relatives, especially the elderly.

Outdoor activities should be curtailed and those who have to be outdoors should take frequent breaks while seeking shade, according to the University of California Extension Service.
