Hannah Storm -- My Eyebrows Are Growing Back!

Hannah Storm's miraculous recovery is still full speed ahead after she was badly burned in a grill explosion -- in fact the ESPN anchor tells TMZ her eyebrows are finally growing back!!!

Storm suffered 1st and 2nd degree burns to her neck and face on Dec. 11 -- when her propane grill erupted into a ball of flames while she was preparing dinner for her family. Storm lost her eyebrows and half of her hair in the explosion. Her left hand was also badly burned.

But Hannah refused to let the incident keep her down -- she returned to the airwaves on January 1 to host the Rose Parade (sporting a wig and freshly painted eyebrows).

Now, Storm tells TMZ ... she's excited about her recovery ... and this weekend at JFK, she pointed out that her eyebrows are already on the rebound.
