Rain in Houston: What You Need to Know
Houston, Mississippi experiences Gulf Coast subtropical and tornado risk. The Houston rain radar delivers real-time NEXRAD data from KJAN (Jackson), updated every 4–6 minutes at up to 250-meter resolution. Storms in this part of Mississippi typically approach from south or southwest, and RainViewer's hyperlocal radar shows their exact position and direction so you can act before conditions change.
A standard forecast covers the broader Mississippi region. RainViewer shows the actual cell over Houston right now — with direction arrows and a 2-hour nowcast so residents and visitors can make real decisions, not guesses.
