The board this morning

Georgia park shooting reported to have wounded teens, still unconfirmed, as flood warnings run from Illinois to Iowa

By The FirstResponders Desk

Good morning. Lead with the mass-casualty item, and lead with what you don't have: a shooting at a park birthday party in Georgia is reported to have wounded a large group of teenagers, and it is not confirmed by any agency. Counts already differ by outlet. CBS News reports the sheriff's office put the wounded at 11 — described as four 18-year-old men, five 17-year-old boys and two 18-year-old women — at Carolyn Crayton Park. ABC News reports a sheriff's figure of 12 wounded and says two groups shot at each other during the party. Treat both figures as early and moving. For EMS and LE, the operational read is a multi-patient scene with mixed ages; for dispatch, expect the count to be revised.

Weather is the confirmed load. The NWS has issued Flood Warnings (Severe) that will shape shifts: NWS St Louis for Calhoun, IL and Pike, MO; NWS Chicago with several warnings for Lake, IL; and NWS Quad Cities for Clinton, IA and Scott, IA. Emergency managers and dispatchers along those counties should assume water rescue and road-closure demand.

Offshore, the hurricane picture stays live. The Oregonian reports Hurricane Nolo was churning slowly south of the Big Island with maximum sustained winds of 90 mph. The Guardian reports Nolo was moving away from the Hawaiian islands but the threat of heavy rain, flash flooding and strong winds persisted, and that Mexico's Baja was bracing for major Hurricane Polo.

Rescue: the Los Angeles Times reports the U.S. Coast Guard rescued a sailor after a 25-foot sailboat ran aground on Santa Rosa Island off Southern California.

Law enforcement: Fox News reports police in San Diego County are hunting a convicted sexually violent predator who vanished after a GPS "tamper mode" alert. In New Jersey, NJ.com reports police say a 51-year-old man is in critical condition after being struck by an SUV early Sunday in Hackensack — a critical trauma patient for the responding EMS crew.

Fire: several reports are on the board that no agency has confirmed — a two-alarm house fire in Virginia, and satellite fire detections over Indiana (151), Mississippi (65), Alabama (60), Louisiana (61), South Carolina (45) and Georgia (29). All are unconfirmed; watch for agency confirmation before committing to a picture. Off the line, Firefighter Close Calls flags a Thomas Jefferson University study on traumatic brain injury and concussion among firefighters, and Wildfire Today reports XPRIZE named winners of its wildfire detection and response competition.

What to watch: agency confirmation and revised counts on the Georgia shooting, flood-warning updates from the three NWS offices, and Nolo's track off Hawaii.
