L.O.
So what about these rumors of FEMA and the military going after each other in Ian aftermath zones...?
I hear silence. I do not listen to the Local Broadcast News and until I saw your question, I knew nothing of this. No one in my County is talking about it on Nextdoor or FB, so I think it is just a rumor without substance.
Reuters posted an interesting map of Ian's rainfall (the "plus" part after 8 inches is questioned for a reason discussed below):
I think Reuters used partial data as the linked article appears to me as speculative with regard to the storm track.
Ian has been called a "500-year" event. For clarification, a "100 [500] -year event" does not mean it will occur exactly once every 100 [500] -years, or that it will not happen again for another 100 [500] years.
The "100-year event" statistically describes the CHANCE of an event in ANY year equal to 1 chance in 100 or 1.0%. Similarly, the 500-year event is 1 chance in 500 or 0.20%. The US Gulf or Atlantic coastline could experience (say) three (3) 100-year events in a single year - EACH event independent and measured in the AMOUNT of rainfall per event. Let's hope not though.
The AVERAGE 100-year rainfall amount in 24-hours is 10.9 inches with a 90% confidence interval between 8.34" and 14.4".
The AVERAGE 500-year rainfall amount in 24-hours is 15.2 inches with a 90% confidence interval between 10.6" and 21.6".
https://hdsc.nws.noaa.gov/hdsc/pfds/pfds_map_cont.html?bkmrk=fl It is noted that both the 100-year AND 500-year 24-hour events have overlapping rainfall amounts within their respective 90% confidence intervals (namely 10.6" to 14.4"). This is not problematic, only coincidental, like Kamala's Venn Diagrams. The actual flooding characteristics are a considerably greater indicator of rainfall and will be reverse engineered in the weeks and months after the storm for a "bell-weather" (clear) understanding of Ian's cumulative rainfall.
Check out the State's river gages.
https://water.weather.gov/ahps2/forecasts.php?wfo=mlb Deep Purple means MAJOR Flooding, as many gages exceed their historic recorded flood stage along the storm's path. Ian was a MAJOR storm event.
Hold your cursor over the gage node on the linked map and that gage will pop up. The gage just below me on Lake Harney, GENF1, has quit working, was still rising on Friday afternoon at 11.71' NGVD '29 datum, and was expected to continue to rise to 12.5' tomorrow afternoon (for 5 DAYS after the event passed) before receding over the next two weeks. That's a LOT of water!
Today, the FDOT closed the State's highway, SR46, between Geneva and Mims due to flood water overtopping the roadway. The last time this happened was 2008, when the highest flood record was set following
Tropical Storm Fay, not even a hurricane, which dumped 20+" of rainfall in 24-hours.
