Safety and Preparedness

There are no active National Weather Service or NOAA weather alerts in effect for Van Alstyne at this time. However, the combination of high temperatures and elevated humidity creates conditions that can be taxing on the body. Residents are advised to stay hydrated and limit prolonged outdoor exertion during the peak heat of the day. Wearing lightweight, light-colored clothing and seeking air-conditioned environments during the hottest parts of the afternoon can help prevent heat-related illnesses. Keep an eye on how the heat index feels rather than just the thermometer reading, as the perceived temperature will be notably higher than the actual air temperature.
