Boston here (home of decaying old red brick pizza oven buildings, not designed for modern summers).
This morning, as we enter a forecast high of 102F real temp, and heat index up to 110, my own old building is trying to get a 5-hour water shutdown of our entire building of ~100 residents, including elderly... postponed until after the scorching peak of the heat wave is over.
Not only do we have neither the architecture nor the acclimation for hot climate, but we don't even know what's ridiculously stupid behavior in such a climate.
