IMPACT Meteorology Unit Banner
The experimental 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.

Isolated showers providing very limited relief to dry conditions

Good afternoon. A weak synoptic scale frontal boundary is draped across central Florida this afternoon. Isolated showers will continue to move east at 25 mph. The showers will briefly increase in coverage and intensity as they collide with the east coast sea breeze, but remain isolated. So far, no lightning has been detected even in the isolated heavier showers that have crossed central and southern Brevard county behind the sea breeze. Isolated showers will continue to move east across portions of Volusia, Seminole, Orange, Osceola and Brevard counties through sunset. A rumble of thunder or cloud to ground lightning strike cannot be ruled out. A few showers may develop along the sea breeze boundary from Vero Beach to Fort Pierce and Stuart.
