How did Hurricane Irma flood Jacksonville?
Irma pushed the St. Johns River to record flood stages at many locations in Duval County in September 2017, and hundreds of people had to be rescued. Floodwaters rushed into city streets and reached up to 5 feet deep in some locations. River salinity data suggest the first rise likely came from easterly winds ahead of the storm pushing seawater upstream, and rain runoff then added to the flooding. The National Hurricane Center called it one of the worst flooding events in the city's 225-plus year history.
What made Hurricane Dora in 1964 so unusual?
Dora was the first hurricane to make landfall over northeast Florida in the 20th century. Its large eye moved over St. Augustine just after midnight on September 10, 1964. Peak winds there were estimated at 125 mph. Tides ran 5 to 8 feet or more above normal along the northeast Florida coast, with over 40 homes lost along the coast. Total storm damage in Florida was estimated at $200 million to $230 million.
Does it ever snow in Jacksonville?
Rarely, but measurable snow fell during the Christmas coastal snowstorm of December 22 to 24, 1989. The Jacksonville NWS office measured 0.8 inches, the second highest storm total on record for the city. Jacksonville Naval Air Station picked up 1 inch, while Jacksonville Beach recorded 2.5 inches. Radar alone will not tell you whether it is rain, sleet or snow, so check the hourly temperatures too.
When is the jacksonville weather radar busiest?
Summer keeps it busiest, with June the wettest month at 7.32 inches at Jacksonville Naval Air Station. Every month from June to September averages 6 inches or more, and the yearly normal is 47.6 inches. November is the driest month at 2.03 inches, followed by February at 2.26 inches. KJAX sits about 11 miles from the city center, so its beam stays low over town and catches light rain well.
When should you check the Jacksonville radar?
