Flex Alert Issued As "Unusually Strong" Heat Wave Hits San Diego

As San Diego braces for an "Unusually Strong" heat wave over the Labor Day weekend, the California Independent System Operator (ISO), which manages California's electric grid, has issued a statewide Flex Alert for Saturday, Sunday, and Monday from 3:00 pm to 9:00 pm.

The ISO's Flex Alert for September 5-7, 2020 was issued in anticipation of high energy demand (primarily from air conditioning) over the holiday weekend as temperatures reach triple digits countywide, including some coastal communities. Overnight temperatures are also projected to be 10 degrees higher than normal, which does't allow buildings to cool down properly. Flex Alert updates can be found here.

The National Weather Service has issued the following excessive heat warning:

10am Friday through 8pm Monday in the county's western valleys, mountains and deserts, where temperatures are expected to range from the high 90s to over 110 degrees.

10am Saturday through 8pm Monday in the county's coastal areas, where beaches are expected to range from the 80s to low 90s and coastal communities will range from the 90s to over 100 degrees.

Residents are reminded to drink lots of fluids and stay out of the sun. NEVER leave children, seniors, and pets in an unattended vehicle.

Beat the heat: County Cool Zones will be open Saturday, Sunday and Monday from 12:00 noon to 5:00 pm at these locations.
