The National Weather Service has issued this moderate-severity alert due to rising temperatures and high humidity levels that will make the heat feel significantly more intense than the actual air temperature.

The relative humidity is at 50%, with a dew point of 72F, indicating quite humid air. Winds are currently blowing at 8 mph, with gusts reaching 6 mph, under a clear sky.

Safety Reminders

With heat index values approaching 108F, it is crucial to take precautions against heat-related illnesses. Stay hydrated by drinking plenty of water, even if you do not feel thirsty. Limit outdoor exertion, especially during the midday hours when the sun is strongest.

If you must be outside, seek shade or air-conditioned spaces frequently. Check on neighbors, particularly the elderly and those without air conditioning, to ensure their safety during this period of extreme heat.
