Hydrologic Outlook issued May 28 at 2:23PM MDT by NWS Riverton WY
ESFRIW Temperatures are expected to reach the mid to upper 80s this weekend. Sunday will be the warmest day, with highs in the upper 80s to low 90s across many locations. Low temperatures will also remain well above freezing with low temperatures in the 40s at elevations above 9500 feet. These warm temperatures will 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

ESFBRO The Brownsville Texas National Weather Service Office has implemented Advanced Hydrologic Prediction Service (AHPS) for the Los Olmos Creek basin in Deep South Texas. AHPS enables the National Weather Service to provide long-range probabilistic outlooks. This service is also available on the internet. In the table below...the 90 through 10 percent columns indicate the chance the creek could rise above the listed stage levels in the next 90 days. Example: The Los Olmos Creek near Falfurrias has a flood stage of 11 feet. There is a 50 percent chance the Falfurrias forecast point will rise above 2.3 feet during

ESFRIW Showers and thunderstorms will continue to develop over Johnson County this afternoon and evening. Weather models depict a nearly stationary boundary, focused on the eastern foothills of the Bighorn Mountains. With precipitable water values in the 0.7 to 0.8 inch range, which is well above normal, it's worth watching this area for training storms and isolated flash flooding. There is a low chance for flooding in any given location, but the low-end potential is there today given the ingredients present. By midnight, thunderstorms and higher rainfall rates are forecast to end, but light rain lingers through sunrise Wednesday, with

ESFAFG A moderate to heavy run of ice on the Porcupine River will be passing Fort Yukon today. The heavy run of ice from Old Crow breaking up on Saturday morning was about 100 miles upstream from Fort Yukon as of 1pm Sunday. Water and ice levels with this run of ice are covering sand bars, but no significant water or ice has been seen overbank. Light runs of ice will continue through the week. The Porcupine River at Old Crow broke up Friday night and jammed just downstream from Old Crow causing moderate flooding before releasing Saturday morning. The

ESFAFG The Porcupine River at Old Crow broke up Friday night and jammed just downstream from Old Crow causing moderate flooding before releasing Saturday morning. As of noon Saturday the Porcupine River had broken up past the US border. The Porcupine River at Fort Yukon is currently ice free, but light to moderate runs of ice can be expected to begin today through the middle of the week with water levels on the Porcupine River rising through the week into next weekend. At this time no flooding is expected as these runs of ice move past Fort Yukon.

ESFAFG The Yukon River continues to hold sections of thermally degraded in-place ice between Beaver and Tanana. These limited sections are slowly breaking up and will continue to create ice runs they are pushed out. Remaining ice should clear out by this weekend.
