Higher than typical October temperatures will impact the Central Valley of California through next week. Moderate to Major HeatRisk is expected this weekend well into next week. Heat of this intensity can endanger anyone without adequate cooling or hydration.
Major Heat Risk exists for portions of the San Joaquin Valley this weekend. The most affected areas will be Bakersfield, up along the Coastal Range and Merced County. Much of the population is affected by Major Heat Risk, especially those without effective cooling or hydration, as well as elderly and infants. Drink plenty of water or sports drink, limit time outdoors during the warmest parts of the day, and use air conditioning during the day.
While this heat will stick around for most of the work week, the ridge will begin to weaken and allow for a trough to move in 🪭. With it, temperatures will FINALLY drop to a more agreeable level 🌡️⬇️. This is still quite a few days out, but relief is in sight!
