Center Weather Advisories

07 Mar 2024 05:30 AM
To support aviation, the NWS has Center Weather Service Unit (CWSU) offices spread throughout the country. These offices issue a number of products that are archived on this website. One of them is the Center Weather Advisory (CWA). The featured map presents a recent CWA issued by the Minneapolis CWSU for some thunderstorm activity clipping northern Iowa on Sunday. The autoplot tool that generated this map isn't all that functional for public usage yet, so the text interface is one of the better places to find these maps along side the raw issuance text. Additionally, the IEM has a shapefile download option for an archive of these alerts.
