Marine Weather and Tide Forecast for Hanksville, UT

DISCUSSION, Issued 1218 PM MDT Thu Jul 16 2026
As an active monsoon surge continues across the region for the entire forecast period, the weather each day across the southern half of Utah will be focused on afternoon and evening convection. Precipitable water values have already exceeded the 98th percentile across many locations of southern Utah and extended ensemble modeling suggests PWs will remain above 90th percentile through at least next Thursday.

While there is no obvious source of lift today in regards to a shortwave trough, convection will continue to develop across the higher terrain through early afternoon. With most parameters at or more preferential for cold pool/shear balance, expect slow moving convection with very heavy rainfall to gradually shift into adjacent valleys with higher available instability. A Flood Watch remains in effect across much of southern Utah this afternoon and evening.

It'll feel a bit like rinse and repeat for southwest and south central Utah Friday afternoon and evening. Little change in the environmental conditions will yield another round of higher probabilities of flash flooding for these areas. A Flood Watch for flash flooding was issued for southwest and south central Utah with this package.

Not seeing much change in relation to the monsoon into the weekend...so future shifts will continue to monitor for expansion of the flood watches into the weekend. This is not the time for outdoor recreationists to plan hikes into/near slot canyons, normally dry washes, slick rock areas. Additionally, those near recent burn scars such as Cottonwood, Monroe Canyon, France Canyon, and Forsyth should continue to monitor for potential warnings and have a plan if a warning is issued.



AVIATION
KSLC...Vicinity showers and thunderstorms may produce variable winds at the terminal between 01-03z, with a better chance of becoming southerly around 02z with periods of gustiness. Typical lighter southeast winds should settle in after 07z and persist through 19-20z. Expecting another round of vicinity storms tomorrow, with a better chance of impacts at the terminal by late afternoon.

REST OF UTAH AND SOUTHWEST WYOMING...Showers and thunderstorms are expected to diminish at the northern terminals before midnight, though periods of showers may persist in the higher terrain. A greater chance of late evening storms exists at the southern terminals, accompanied by erratic and gusty winds through the early morning hours.



FIRE WEATHER, Issued 1218 PM MDT Thu Jul 16 2026
An ongoing monsoon surge will continue to bring the threat of heavy rainfall to much of southern and portions of eastern Utah through at least the weekend, and potentially into early next week. For areas more removed from this surge across northern and west central Utah, coverage of any thunderstorms will be less across valley locations. Humidities in the 20-30% range across the northern and western valleys will further increase this weekend to around 30-40%.

SLC WATCHES/WARNINGS/ADVISORIES
