If Hermine had another night to spend over the Gulf, it would probably really get cranked up, but its remaining several hours over water will occur at a time of day when rapid intensification isn't usually observed as frequently. Based on radar, Hermine seems to have turned to the left somewhat, though it remains to be seen if that trend will hold until landfall. Looks like another plane is on the way to investigate the storm.

Hermine has the potential to be a a major heavy rain producer for parts of the U.S. southern plains if the forecast track holds and it doesn't get hung up over the high terrain of NE Mexico. The risk of isolated tornadoes will increase tonight along and east of the track. The remnant low is forecast to continue into north TX and OK, where it may interact with an old frontal boundary and create an enhanced threat of excessive rain and a few tornadoes. If the NAM and GFS are to be believed, ex-Hermine will continue to pose a compact but significant heavy rain threat into parts of the Midwest toward the end of the week.
