SAN DIEGO (FOX 5/KUSI) — Parts of eastern San Diego County and Imperial County will be under an extreme heat warning later this week, while wildfires burning in central California brought some cloud coverage to San Diego over the weekend.
Satellite and radar showed smoke traveling south from the Gifford Fire burning in San Luis Obispo and Santa Barbara counties that mixed with coastal cirrus clouds moving east from the Pacific Ocean to create hazy conditions across San Diego County on Sunday, according to the National Weather Service.
Much of San Diego County remained at a normal to moderate air quality Sunday, Airnow.gov reports, meaning those unusually sensitive to air pollutants could be impacted and are urged to reduce time outdoors.
Heat Risk/Extreme Heat Warning
Portions of Southwest Arizona and Southeast and Southern California will be under an extreme heat warning from 10 a.m. Wednesday to 8 p.m. Friday, the National Weather Service reports.
The heat will peak Wednesday into Thursday, with temperatures expected to reach 106 to 118 degrees in those areas.

HeatRisk serves as another NWS tool that can be used to protect lives and property from the potential risks of excessive heat, being especially useful for those who are more easily affected by heat or those who provide support to those communities of heat-sensitive individuals. HeatRisk ensures that communities have the right information at the right time to be better prepared for upcoming heat events.

The National Weather Service forecasts Ramona has a 65% chance temperatures could reach over 100 degrees on Thursday.

When in an area under an extreme heat warning, the National Weather Service advises to limit time spent outdoors, drink plenty of water, wear lightweight and loose-fitting clothing and to keep an eye out for signs of heat exhaustion and heat stroke.
Public cooling centers are available in San Diego County for anyone needing a safe place to stay while extreme heat warnings are in place.
