Debby does not strengthen any before landfall. This morning the path for Debby took the story straight west for a possible Texas landfall. So this storm bears watching in case it's path radically changes again.
Update - As of 11am Eastern Time on June 26 TS Debby is proving why forecast prediction is still something of an art. Predicted landfall is now about 8am Eastern Time on Wednesday in Levy county Florida. North of Tampa and by 4pm Eastern will be passing north of Ocala. Does not look like any strengthening will occur before landfall.
But stay tuned.
