Parts of southeastern South Dakota, including areas in Lincoln and Minnehaha counties, could see several inches of rain between June 24 and June 26, according to the National Weather Service office in Sioux Falls.
The office is urging residents to make sure their sump pumps are ready to handle the potential deluge, and to check storm drains and gutters for potential obstructions.
How much rain are we talking about?
As of about 4:30 p.m. June 24, areas were expected to see 2 to 4 inches of rainfall accumulations, but amounts could be higher locally.
Where is the greatest chance for more than 4 inches of rain?
The NWS is predicting areas in northeast Nebraska and northeast Iowa have the highest chance for more than the expected 4 inches of rainfall.
What time will rain start and stop?
The first round of heavy rainfall is expected the night of June 24, with more sporadic rain expected throughout the day June 25.
That night, however, the second round of heavy rain is expected to hit, with additional showers June 26.
Watch for ponding water on roads and poor drainage, the NWS warned.
Small rivers and streams could also rise.
