The Impact Weather Update (IWU) provides a chronological series of discussions to detail conditions expected over the next 8 hours. The IWU was designed to supplement existing NWS products by providing more frequent information in a less formal format. IWU entries will only be available when workload permits, most often on weekdays between late morning and early afternoon. When severe weather becomes imminent, IWU posts will often cease due to increasing workload. East Central Florida counties include: Volusia, Seminole, Lake, Orange, Brevard, Osceola, Indian River, Okeechobee, Saint Lucie and Martin. Please provide us with your comments concerning the IWU.
