Hi everyone,

It is blazing hot in my area and we are currently under an excessive heat warning. Temps will top up at 101 and about the same tomorrow with very high humidity.

I've dealt with this kind of weather many times, but I've never taken a road trip under such a warning. I have a friend that wants me to come visit this weekend, and I'm a bit torn if I should go or not. It would be a 230 mile drive and my fear is worst case scenario. My car breaks down, I have no AC and I'm stranded in this blazing heat. There are large paths of interstate with no towns on this route so I could be stuck for an hour or more waiting for help. If the heat index is 110-115 and it gets 10-15 degrees hotter in my car, that has me concerned. Could I avoid heat illness as long as I have plenty of water?

I do have two cases of bottled water in my car and I plan on freezing a bottle before I leave. My car has never broken down so the odds are in my favor. What would you do in my situation?

Do you have to drive during the hottest part of the day? Either way I wouldn't cancel, odds are that your car won't break down. I'd definitely bring the water just in case though.

I wouldn't worry if your car is in good shape and you've had problems. To be on the safe side, I'd bring half a gallon of water. If the sun isn't high, the heat wouldn't be dangerous just unpleasant.

I would buy a whole gallon just in case. Keep it cold in the fridge. Also, make sure your car engine is filled up with coolant fluid. Engines overheat easier in extreme heat.

It really makes very little difference. The operating temperature of an engine is far higher than any ambient temperature. If a car won't overheat at 90 F, it definitely won't overheat at 100 F as well.

You would know more about this than me, lol. It's good to have it filled up regardless though.

Your car's fluids and coolant temperature is much lower, it can overheat, though 100°F should be ok if the car's working right unless you're driving it hard (such as up a long, steep hill, or keep gunning the accelerator unnecessarily)

Besides making sure your car is in tip-top shape (which should be done before any road trip) and bringing at least a gallon of water for you to drink, I would suggest a small cooler filled with ice. And bring along some clean wash clothes as well. You can get them wet and cool down your body quickly that way if needed.

I certainly wouldn't cancel my trip. It gets to 100F heat index - excessive heat warning - around here several times during the summer and we keep going about our regular lives. Just think... 200 miles away it might be cooler.
