So it turns out that southern Florida gets twice as many tornadoes during El Niño years, but northern Florida doesn't. When you average them out, it's only slightly higher, which leads people to think El Niño tornadoes aren't a big deal in Florida. accuweather.com/en/severe-we…

Significant tornadoes have occurred across central FL during past strong El Niño events (1998 & 2007). The greatest threat of strong tornadoes (EF-2+) is typically between Feb-Apr.
Does your family know where to shelter if a warning is issued?

A 5-inch plus rain swath about 20 miles long by 10 miles wide over mountainous terrain was enough to trigger major flash #flooding in Copperhill, TN and McCaysville, GA.

Great Info-graphic @TimBuckleyWX
If we look at other very strong El Niño winters, there’s a clear signal for wetter weather.
Snow? As always, less clear.
In these 4 very strong El Niño winters 3 saw snow, one didn’t, and none had above avg snowfall.
I think we’ll have lots of systems to track, but we’ll have to try and line up the cold air just right.

‼️ 50 Year Record Broken in Ft Lauderdale! 🌊
Water levels reached 2.51 Ft above mean higher high water, breaking the record for highest water in Port Everglades. That beats #hurricane Dorian and Nicole. Palm Beach also set its highest level on record in 56+ years. (Palm Beach broke record too - graph in thread)
This is due to persistently strong onshore winds, full moon, favorable lunar phase, and sea level rise due to a warming climate. The number of “Sunny day” floods are increasing each year recently. (Yes I know it wasn’t exactly sunny) 🧵 1/
