Key Messages
- Gusty southwest winds are expected each afternoon and evening across Utah and southwest Wyoming through the end of the work week. With minimum relative humidities approaching critical values in pockets of western Utah, this will result in some locally critical fire weather conditions.
- An influx of tropical moisture over the holiday weekend will increase the risk of flash flooding into early next week, particularly on Sunday across central and southern Utah.
