LOS ANGELES, CA — Record-breaking heat is expected across the San Fernando Valley Wednesday, with temperatures forecast to climb above 110 degrees in some communities as a prolonged heat wave continues, according to the National Weather Service.
Van Nuys is forecast to reach 107 degrees, topping the record of 105 degrees set in 2010, while Woodland Hills could hit 111 degrees, surpassing its 1981 record of 109 degrees.
Burbank could reach 105 degrees. The Burbank record for the date is 111 degrees, set in 1944.
Several other communities could also set new daily records.
Downtown Los Angeles is forecast to reach 101 degrees, which would break the Aug. 26 record of 98 degrees set in 1981.
The extreme temperatures are part of a prolonged heat wave expected to keep much of Southern California dangerously hot through the end of the workweek.
High and low temperatures are expected to continue rising through Thursday, reaching as much as 10 to 15 degrees above normal, according to the National Weather Service. Little change is expected Friday.

An extreme heat warning remains in effect across much of the region through 8 p.m. Friday, including valleys, mountains and some coastal areas.
Temperatures could reach as high as 112 degrees in the hottest valleys and mountain areas. Even inland portions of normally cooler coastal communities could climb into the 90s or low 100s.
The heat is also contributing to elevated wildfire danger in parts of Los Angeles County. A red flag warning remains in effect through 3 p.m. Friday for the San Gabriel Mountains and areas along the Golden State and Antelope Valley freeway corridors.
Forecasters warned that temperatures in areas covered by the fire warning could reach 106 to 108 degrees while humidity falls below 10% in some locations.
Southern California Edison has also warned that Public Safety Power Shutoffs could affect about 3,100 Los Angeles County customers, primarily near Malibu, the Santa Monica Mountains Recreation Area and northern communities including Castaic and Sandberg.
The heat has already produced records. Los Angeles International Airport reached 85 degrees Tuesday, breaking the previous record for the date of 84 degrees set in 1981.
National Weather Service forecasters also said this has been the warmest summer on record in downtown Los Angeles. The average downtown temperature from July 1 through Monday was 88.4 degrees, surpassing the previous record of 88.1 degrees set in 1886 and matched in 1998.
Health officials urged residents to drink plenty of fluids, remain in air-conditioned spaces when possible, avoid strenuous activity during the hottest parts of the day and check on relatives and neighbors.
Los Angeles residents can call 311 for information about cooling centers. Los Angeles County also maintains cooling centers, pools and splash pads for residents seeking relief from the heat.
