Hydrologic Outlook issued June 19 at 3:06PM AKDT by NWS Juneau AK

ESFAJK Northern Lynn Canal region will be warming into the 70s by the weekend, while snow levels rise to 7000 feet or higher. This will increase the amount of snowmelt running into the streams and rivers. This will raise the water levels in them, and in some case could bring the levels to bankfull or beyond that. The Taiya and Skagway rivers are anticipated to see increases, but at the time are approaching bankfull. The Haines zone was removed from this outlook due to the issuance of a Flood Advisory for the Chilkat River.

ESFAJK Some areas in the Haines and Skagway Boroughs will be warming into the mid to high 70s by Friday and increasing into the weekend, up to the low 80s along the Haines Highway area. Snow levels are expected to rise to 8000 feet or higher. This will increase the amount of snowmelt running into the streams and rivers. This will raise the water levels in them, and in some cases could bring the levels to bankfull or beyond. In particular, the Chilkat River forecast has been gaining confidence on reaching levels to around minor flood stage. The Taiya and

ESFMSO Where: Flathead and Lincoln Counties in northwest Montana What: Confidence is trending higher that a prolonged rain event will produce 2 to 4 inches of rainfall in a 48hr period, starting Friday evening and lasting into Sunday. The result will be the potential for rock and debris slides along steep terrain in Glacier National Park and Forest Service roads in the Flathead and Kootenai National Forests. Low land ponding of water will be possible in poor drainage areas. Consider delaying backcountry travel this weekend, or plan accordingly as conditions will be cold and wet, and moderate to heavy snow

Hydrologic Outlook issued June 3 at 9:29AM MDT by NWS Pueblo CO

ESFPUB Risk of enhanced runoff and elevated stream flows from snowmelt ...EXISTING CONDITIONS... Warmer temperatures in the upper Arkansas River Valley has led to accelerated melting of the remaining, near normal mountain snowpack. This trend will likely continue for the remainder of the week. ...PRECIPITATION... Approximately 0.25 to 0.5 inches of rain over the next 72 hours may fall over much of the area of concern. The potential for some rain- on-snow, along with warmer temperatures, could accelerate melting of the remaining snowpack. ...STREAMFLOW CONDITIONS AND RUNOFF FORECASTS... Streams and rivers in the area could see elevated flows of swift

Hydrologic Outlook issued June 1 at 1:06PM MDT by NWS Riverton WY

ESFRIW Temperatures are expected to reach the upper 80s to low 90s across many locations Sunday. Low temperatures will also remain well above freezing with low temperatures in the 40s at elevations above 9500 feet. These warm temperatures will continue to lead to an increase in the rate of mountain snowmelt. Most mountain snowpack below 9500 feet has melted out, however, high-elevation mountain snow water equivalent (SWE) above that level still remains. With the expected warm temperatures, a significant portion of that high-elevation snowpack is expected to continue to melt through Sunday night. Minor flooding of small streams and creeks
