Today is one of the few hot and humid days that the Twin Ports experiences during a typical summer season. High temperatures are expected to reach the upper 80's and even low 90's in some areas and relative humidities will be in the 60 to 70 percent range. That would create a heat index value of near 100. The heat index is the summer equivalent of the winter wind chill chart. Just like brisk winds make it feel colder in the winter, high humidities make it feel hotter and more uncomfortable in the summer. Since we are not used to such heat on a regular basis, keep in mind it can be a threat to your health. If you need to be outside for long periods of time, avoid strenuous activities, take frequent breaks in the shade and drink plenty of water. Never leave kids or pets in a closed vehicle and try and stay where it's air conditioned if possible.
