Hydrologic Outlook issued May 7 at 2:39PM MDT by NWS Billings MT
ESFBYZ Warm temperatures are forecast through early next week. This is expected to increase snowmelt across area mountains, resulting in a significant increase in flows on area rivers and streams by this weekend. While flooding is not anticipated on larger rivers and streams, there is a chance that some smaller streams and creeks could reach bankfull in and near the foothills, producing minor flooding. At the very least stream flows will be much higher with the increased snowmelt. Water rises will occur first on small streams and creeks flowing out of the foothills, eventually arriving on larger rivers and streams.

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 2.4 feet during

ESFTAE Multiple waves of rain and storms, locally heavy, is expected across the area beginning Thursday and lasting at least into the first part of next week. This is all thanks to an area of low pressure that will meander in the northern Gulf and central Gulf Coast region for several days. While confidence is increasing in the threat of heavy rain and flash flooding, the exact placement and rainfall totals are still relatively low confidence. The current most likely forecast calls for a widespread 4 to 8 inches across the forecast area from Thursday through Monday. This does lie

ESFILX This hydrologic outlook includes the following river in Illinois: Embarras River... The following river information is based on future predicted rainfall. The exact amount, intensity, timing, and location of the rain that will occur is still uncertain. These outlook stages are provided to show what may be expected if the forecast precipitation occurs. Once there is more certainty about the river forecasts, a flood warning or statement will be issued if the threat materializes.

ESFAFG An ice jam above the mouth of the Fortymile River remains in place and is likely to continue eroding from the downstream side as water levels at Dawson are gradually increasing. The ice jam below Calico Bluff cleared overnight. Eagle and other locations along the Yukon that currently have open water can expect ice runs and rising water levels when this upstream jam releases. No flooding is expected at Eagle. This hydrologic outlook will expire at noon on May 5 and not be continued unless there is a change in the condition of the Canadian ice jam.

ESFPPG A prolonged period of widespread showers is forecast to impact the Samoa region beginning Tuesday and continuing through Thursday, with rainfall intensity and coverage expected to increase significantly by Friday and into Saturday. An active trough causing this extended duration of rainfall raises the potential for localized and widespread flooding, particularly in low-lying and poor drainage areas. Peak impacts are anticipated Friday through Saturday, when the trough is most active. Rainfall totals over the event period may exceed thresholds for flash flooding, especially in areas that have already experienced saturated soil conditions in previous weeks. In addition, landslides will

ESFAFC As of approximately 19:30 AKDT Saturday, McGrath ice started running. Water levels have risen but remain below the bank. Ice is very weak and disintegrating as it moves. McGrath has no flood concerns at this time. As of approximately 20:30 AKDT Saturday, Stony River has ice running past. Water levels have risen 3-4 ft and are expected to continue to rise. Residents are not expecting the water level to reach airstrip level. This ice run is more dense, with more water volume, a lot of wood, and running faster than Thursday night. This ice run is most likely ice

ESFAFG An ice jam above the mouth of the Fortymile River has remained in place since Thursday. With the cooler temperatures snowmelt contribution to the Yukon has not increased water levels at Dawson so this jam has been stable and will likely erode from the downstream side. In this scenario, Eagle and other locations along the Yukon that currently have open water can expect eventual ice runs accompanied by a significant rise in water levels as this jam releases and potentially adds to the current jam downstream of Calico Bluff.

ESFAFC As of 19:15 AKDT Thursday, ice began running past Stony River and water levels rose approximately 2 ft. As of 21:00 AKDT the ice continues to run and the water levels are steady. The River Watch team on Wednesday saw no intact ice until 8 miles upstream of the Tatlawitsuk River. River Watch also confirmed on Wednesday that the Tatlawitsuk, Swift, and Stony rivers were all free of ice. On Thursday evening, local residents in Stony River assume this run is intact ice that was released between Devils Elbow and upstream of the Tatlawitsuk River. At this time, the
