NORWALK - It was an uncomfortable day outside today, but it wasn't quite as blistering as some had expected.Public officials put emergency procedures into effect today, but they apparently weren't needed. Many communities opened emergency cooling centers for neighbors without air conditioning, but temperatures were lower than expected, and the sun was often blocked by clouds.Still, health officials say that people ? especially the elderly and those with heart or respiratory problems ? are still at risk in these warm temperatures. They say it's important to stay hydrated and not overdo it in the heat.
