Communities in California are at risk of more wildfires as the weather conditions can become critical this week. Low humidity, increasingly hot, dry air, and gusty winds can create a high risk of fires in California from Wednesday to Friday (October 14-16, 2020).

Residents are advised to exercise extreme caution to prevent new wildfires in this area. Any outdoor burning activities must be carefully avoided. If new fires appear, they are likely to spread at a dangerously rapid pace.

A heat advisory has been issued from Tuesday until Friday, with temperatures as high as 90 predicted at lower elevations. To prevent heat illness, locals are advised to avoid the sun, stay in air-conditioned areas, and make sure they drink enough water.

On Tuesday, October 13, warming temperatures and gust winds can create elevated fire weather conditions in Southern California during the evening and overnight.
