The National Weather Service (NWS) in St. Louis, MO has issued a flood watch and hazardous weather outlook for parts of Illinois and Missouri, highlighting the possibility of flash flooding due to excessive rainfall and a series of strong to severe thunderstorms expected to hit the area. Residents are advised to monitor forecasts closely and be prepared for adverse weather conditions that could lead to flash floods.

According to the detailed forecast, the likelihood of showers and thunderstorms remains high through the evening hours of today. The NWS states, "Showers and thunderstorms are expected through late this evening. Additional rainfall amounts of 1-2 inches are favored." With the saturated ground from previous rainfall, the risk of flash flooding escalates, particularly in low-lying and flood-prone areas.

The flood watch is in effect through late tonight for numerous counties across the two states, including Greene IL, Macoupin IL, Bond IL, Calhoun IL, Clinton IL, and regions like Saint Louis MO, Saint Louis City MO, and Jefferson MO. The NWS warns of "excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations."

The hazardous weather outlook extends through the week, with the potential for more showers and thunderstorms from Tuesday night to Friday night. Spotter activation is expected later in the day, with the NWS asserting that the strongest thunderstorms "will be capable of large hail, damaging winds, and tornadoes." Standing at the ready, authorities are taking the necessary precautions to safeguard against the natural threat posed by such severe weather conditions.
