A look at post-Tropical Cyclone #Isaias and where it is now. In the U.S., flash, urban, and river flooding is possible in some areas. Possible tornadoes, too. Remnants will reach Ontario and Quebec on Sunday, but it won't be a washout. #ONwx #MeteoQC www.theweathernetwork.com/en/news/weat...

Now that's better shot, (higher☀️angle) Even tho Hurricane Isaias is now post tropical & in transition, it still carries some of it's structure of it's former self. That Cirrus shield entering SONT (or what's left of it) was part of it's hi-level outflow structure #onwx #onstorm

Latest Eastern NA radar + Satellite view-Post-Tropical Cyclone Isaias continues it's journey northward. The "primary job" of hurricanes-in a "nutshell"-to redistribute heat/moisture thru-out this blue dot & "try" to balance/regulate the planet's climate. Good Luck!-tuff job to do #onwx #onstorm
