How to check current conditions
People in South Dakota can find official, current weather alerts for the state through the NWS active alerts page.1 The page also links to related NWS products, including excessive rainfall, river flooding, thunderstorm and tornado outlooks, and winter weather outlooks.1
A live NWS radar viewer is also available for tracking storm activity by location.7
Understanding the warning language
Weather Alert Watch, which draws directly from NWS bulletins, explains that alerts state what the National Weather Service issued, where it applies, when it ends, and what the bulletin instructs people to do.4 The service also notes that a tornado warning means a tornado has been indicated, based on radar or a spotter report.4
By contrast, a flash flood watch means conditions are favorable for flooding but flooding is not certain or imminent, while a flash flood warning means flooding is imminent or already occurring.4 Weather Alert Watch cautions that alert counts describe NWS products in the latest collected state and are not a measure of personal danger, and it recommends using the alert text and official affected zones as the primary source of information.4
What to watch next
Weather Alert Watch also logged severe thunderstorm warnings for counties in Arizona and Ohio around the same period.4 Rural residents in northeastern Meade County and west central Ziebach County were the areas specifically named in the Monday evening bulletins.2,3
