Recommendation
Drive early morning between 7:00am and 10:00am when temperatures are 83-90F, and in the evening between 7:00pm and 9:00pm as temperatures fall, avoiding the 12pm-6pm peak heat and the 4pm-6pm storm onset. Check coolant, tire pressure and battery before driving, carry water, never leave children or pets in the vehicle, and pull over safely if a thunderstorm downpour reduces visibility.
