99 - and it's associated trough - was a very prolific wind-maker while approaching the coast. Ship report from very near the center of circulation late overnight came in at 34 knots, and an oil platform with an anemometer at around 400 feet was blasted by hours and hours of sustained winds between 40 and 67 mph, with a pronounced wind shift noted in its obs during passage. Pressure in 99 looked to have dropped to about 29.65 or so, before coming ashore.
Now inland, it has already had enough spin of its own, combined with a few slugs of moisture, friction and daytime heating, to pop one tornado in Buna, Tx. this morning (inland from the uppermost Tx coast.) SPC has had this to say about it in the Day 1:
LASTLY...ANOTHER ZONE OF ENHANCED SVR THREATS WILL EXIST FROM THE UPR TX COASTAL REGION NWD INTO LA AND AR ASSOCD WITH A PLUME OF RICH TROPICAL MOISTURE SURGING NWD WITH A GULF IMPULSE. MODEST LOW-LEVEL WIND/SHEAR PROFILES ALREADY IN PLACE WILL CONTINUE TO IMPROVE WITH TIME AS THE SRN PLAINS UPR JET PUNCHES EWD AND LOW-LEVEL SLY FLOW RESPONDS. HIGHEST POTENTIAL FOR EMBEDDED SUPERCELLS WITH TORNADOES...SOME STRONG...WILL SPREAD NEWD FROM THE UPR TX COAST/WRN LA AT MID-DAY AND REACH THE MID-SOUTH/OZARKS BY TONIGHT.
