Los Alamos, California
Community in Santa Barbara County, California* WHAT...Temperatures up to 95 expected. * WHERE...Coastal areas of southwest California * WHEN...Until 8 PM PDT Saturday. * IMPACTS...Hot temperatures may cause heat illnesses.
Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. In the event of a nearby wildfire, smoke may increase heat and physical stress. If smoke impacts your area; 1) Have a cooling plan in place as smoke could limit your ability to cool your home through open windows and 2) If you have air conditioning, set on air recirculation within the home to avoid smoke exposure. Local officials may have additional guidance.

The week. The warmest day ahead is tomorrow, near 92°, and the coolest Wednesday, near 67°. Rain is likely Tuesday (50%) and Wednesday (53%).
The sky now. The Moon is a waxing crescent, 26% lit, and sets at 9:46 PM. The next full Moon is Sunday, Oct 25. Look for Saturn, bright in the east-southeast. A planet shines with a steady light where the stars around it twinkle. The Orionids meteor shower is active, peaking around Oct 21: at its peak, up to about 20 meteors an hour can be seen from a dark site. The sky is forecast to stay clear: a good night to look up. The day is 11 hours 20 minutes long, 2 minutes shorter than yesterday.
