Are there any severe weather alerts for your area? You can find out on the map below.
Remember, there’s a difference between “monitoring” and “warning.” A “watch” is issued to prepare the public for the potential for severe weather. “Warning” means it’s time to take precautions to protect yourself from severe weather.

Heat index forecasts are not the same as air temperature forecasts.
The heat index takes into account heat and humidity. Looking at these weather elements together is crucial because they work together to affect the amount of evaporation from sweat. When sweat evaporation decreases, outdoor activity becomes more dangerous. The higher the relative humidity, the hotter you feel.
Heat index data is updated from May through September.

How much of Arizona is in the middle of a drought? This map will show you. Remember, drought is measured against what is normal for the area, so a desert is not always in drought just because it is a desert.
When studying short-term drought, the U.S. Drought Monitor focuses on one to three months of precipitation. In comparison, six to 60 months of data can be used to determine whether an area is experiencing a long-term drought, according to the National Drought Mitigation Center.
But the U.S. Drought Monitor doesn’t rely solely on rainfall. The National Drought Mitigation Center collects information about precipitation, lake and reservoir levels, soil moisture, groundwater, and vegetation health, among other factors, to determine whether drought conditions exist.
New data is added to the U.S. Drought Monitor map every week.
