Heat Advisory: Tuesday morning through Thursday evening
NWS Los Angeles/Oxnard issued a Heat Advisory covering the Western San Fernando Valley (zone CAZ372) along with Calabasas/Agoura Hills, the Eastern San Fernando Valley, the Santa Susana Mountains and other Southern California zones. The advisory runs from 10 AM Tuesday, August 18, to 8 PM PDT Thursday, August 20. The NWS describes high temperatures of 92 to 105, with most areas seeing peak heat Wednesday and Thursday, and overnight lows from the upper 60s to lower 70s at lower elevations and the mid 70s to lower 80s in the foothills and mountains. The agency notes hot temperatures may cause heat illnesses and that warmer-than-normal low temperatures will add to heat discomfort. NWS guidance in the alert: drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, check on relatives and neighbors, wear lightweight and loose-fitting clothing, and limit strenuous activity to early morning or evening. The alert adds that the advisory may need to be extended into Friday for parts of the forecast area, though there remains considerable uncertainty at this time.

Highways: one Caltrans closure listed in the West Valley
Caltrans District 7's lane closure feed, last updated 5:01 AM on 08/17/2026, lists one item within the West Valley: a Northbound 101 lane closure from Winnetka Avenue to De Soto Avenue, with 1 of 5 general purpose lanes closed due to tree removal (Closure ID W101NA, Log 1). The record shows an expected end time of 11:01 AM on August 16, 2026, so it may already have been lifted; Caltrans records remain in the feed until cleared. Other Los Angeles County entries in the same feed are outside the Woodland Hills / Canoga Park / West Hills / Chatsworth area, including a Westbound 134 lane closure near Route 5 and a Southbound 5 full closure near Paxton Street for accident investigation. Caltrans QuickMap is the source's live reference for statewide and state highway conditions.
