This outlook covers south central Indiana, central Kentucky, and the Ohio River from Madison, Indiana to Tell City, Indiana. The flood risk in the middle of the Ohio Valley is normal to below normal for this time of year. Minor flooding is expected due to rainfall and thunderstorms with isolated moderate flooding possible. This outlook is valid through May 2024. In Table 1 below...the current (CS) and historical (HS) or normal probabilities of exceeding minor...moderate...and major flood stages are listed for the valid time period. CS values indicate the probability of reaching a flood category based on current conditions. HS values indicate the probability of reaching a flood category based on historical or normal conditions. When the value of CS is more than HS...the probability of exceeding that level is higher than normal. When the value of CS is less than HS...the probability of exceeding that level is lower than normal. ...Table 1--Probabilities for minor...moderate and major flooding...

This is the final hydro outlook for Spring 2024. $$ AMS ####018010824#### FGUS73 KBIS 141613 ESFBIS NDC009-013-023-049-061-069-075-079-101-161400- Probabilistic Hydrologic Outlook National Weather Service Bismarck ND 1113 AM CDT Thu Mar 14 2024 ...SPRING FLOOD AND WATER RESOURCES OUTLOOK... This Spring Flood and Water Resources Outlook is for the Souris River Basin of North Dakota, covering the period of 18 March through 16 June, 2024. This is the third and final edition of the Spring Flood and Water Resources Outlook. On 28 March, the NWS will revert back to routinely issuing of flood probabilities on, or around, the fourth Thursday of every month. The following message has four sections. The first provides some text on the highlights of this outlook and conditions affecting the local hydrology. The second section gives the current and normal/historical risks of flooding as determined by the Ensemble Streamflow Forecast model of the National Weather Service. The third section gives the current probabilities for reaching flood stage at the listed forecast locations. And finally, the fourth section covers the risk of the river sites falling below the listed stages. ...Flood Outlook Highlights... The snowpack across the Souris River basin has been in the process of melting its snowpack on and off again over the past few weeks. In general though, the North Dakota portion of the basin will largely be free of substantial snow cover by the end of this second full week of March. At this point, no flood concerns have arisen, but forecast points such as Towner and Bantry on the Souris River, or Willow City on Willow Creek, still have a fairly decent chance of minor flooding. Overall though, widespread flooding at this point does not appear to be a significant concern without remarkably large amounts of spring rain. ...Snowpack Conditions... The snowpack, along with its associated Snow-Water Equivalent (SWE) had received a significant boost over the past couple of weeks from a couple of notable winter storms. However, it is still widely well below normal to somewhat below normal across the entire basin. And again, since the region has been experiencing periods of well above normal temperatures, significant loss of the snowpack has already been observed and is expected to continue over the coming several days. ...Soil Conditions... Soil moisture values across the Souris River Basin are very high in the Long Creek watershed and somewhat above normal to near normal in other parts of the Souris River basin. Frost depth is highly variable this year as a mix of very warm weather in December and a good part of January has helped prevent extensive freezing of the soil, but up to 30 inches of frost depth has been observed in some areas of the basin within North Dakota. ...Current Drought Conditions... The U.S. Drought Monitor reflects D0 (Abnormally Dry) to D1 (Moderate Drought) across the Souris River Basin of North Dakota. Given the time of year, no significant impacts are noted with the current drought designations. However, concerns with increased drought designations going into spring are warranted, especially since climate outlooks and near-term forecasts do not favor a change in existing trends anytime soon. ...Reservoirs and Natural Wetlands... Lake Darling above Minot along with the Canadian reservoirs behind Grant Devine and Rafferty Dams have their full flood control storage available for spring runoff. The majority of natural wetlands and lakes also are at, or near normal water levels going into spring. ...Weather Outlook... The Climate Prediction Center 6-10 and 8-14 day outlooks favor below normal temperatures and above normal chances for precipitation. That generally carries the state through the remainder of March, however the weeks 3-4 outlooks bring back a fairly strong favoring of above normal temperatures with a slight to strong favoring of below normal precipitation. Looking longer term at the three-month outlook for March, April, and May...a favoring for above normal temperatures with precipitation placed in the equal chances category for above normal, near normal, or below normal precipitation. ...Ice Conditions... After recent warm weather, not all rivers remain covered in ice. Lakes and wetlands are generally still ice covered, but thickness is generally less than normal and as runoff is currently being generated, ice stability, thickness, and quality is lessening with each passing day. In Table 1 below, the current (CS) and historical (HS) or normal probabilities of exceeding minor...moderate...and major flood stage are listed for the valid time period. CS values indicate the probability of reaching a flood category based on current conditions. HS values indicate the probability of reaching a flood category based on historical or normal conditions. When the value of CS is greater than HS...the probability of exceeding that level is higher than normal. When the value of CS is less than HS...the probability of exceeding that level is lower than normal. ...Table 1--Probabilities for minor...moderate and major flooding...
