Florida's Space Coast Hit With Half a Year's Rain in 36 Hours
Up to 27 in (Radar)
Southeastern Brevard County recorded 15–20+ inches of gauge rain and radar estimates up to 27 inches in 36 hours — roughly 50% of an average year's rainfall.

Palm Bay, West Melbourne & Grant-Valkaria Under Water
50% of Annual Rain
Brevard County averages ~54 inches of rain per year. Receiving 15–27 inches in 1.5 days overwhelmed canals, washed out roads, and forced shelter-in-place alerts.

Record-Warm Southwestern Atlantic Fueled a Moisture Firehose
+7% Moisture / °C
A deep onshore flow tapped record-warm waters in the southwestern Atlantic, pushing atmospheric Precipitable Water Values past the 99th climatological percentile.

Weak Mid-Atmosphere Winds Locked Storms Over One Strip
36-Hr Training Bands
Weak steering winds through the middle atmosphere (500–700 mb) prevented rainbands from moving inland, causing cells to 'train' repeatedly over Palm Bay.

How Nov 2026 Compares to Tropical Storm Fay (2008)
2008 vs. 2026
Before November 2026, Brevard County's modern 27-inch benchmark was Tropical Storm Fay (Aug 2008) — which took 4–5 days, whereas Nov 2026 unfolded in 36 hours.

27 Inches on One 2,500 Sq Ft Roof = 42,075 Gallons of Water
42,075 Gallons
At 20 to 27 inches of rainfall, a single 2,500-sq-ft Florida home sheds 31,000 to 42,075 gallons of stormwater in 36 hours — overwhelming 10-year street drains.

Why High Ocean Levels Slow Gravity Canal Drainage
Tailwater Blocking
Elevated Atlantic sea levels and onshore winds raise lagoon tailwater stages, reducing the hydraulic gradient needed for gravity-fed coastal canals to drain.
