Weakening "Debby" approaching the Fl. Big Bend...very heavy rain & isolated tornadoes for the First Coast....daily record rainfall for June 25th at JIA of 7.36" (old record for the date was 2.92" in 2008)
** A significant flooding threat for the First Coast...isolated tornadoes into Tue.**....while winds won't be extreme, it won't take as much as it would typically take to uproot trees given the saturated soil.....
Dry air (see 2nd satellite [water vapor] image below) & westerly shear has had its way with "Debby" leaving the tropical cyclone in a shambles when it comes to organization. The storm should soon be ashore near the Fl. Big Bend but a broad & long southerly fetch of winds to the east of the center will continue to pull tropical moisture northward across Fl. & the First Coast into Georgia. The result will be profound effects NE Fl. & SE Ga. in the form of major flooding with near record flooding possible in some areas. For the First Coast
...heavy rain & a few t'storms will occur into Wed. with the potential for storm totals of 10-20 inches, locally up to 25"!! resulting in a significant flooding threat along with at least isolated tornadoes.
Saturated soils will allow for easily uprooted trees & scattered power outages.
"Debby" should continue to weaken on its transit near & across Fl. before eventually emerging in the Western Atlantic by Thu. or Fri.
