NHC thinks she's on her way out
...KAREN'S WIND FIELD BEGINNING TO UNRAVEL...
...EXPECTED TO BECOME A REMNANT LOW BY SATURDAY...
Data from aircraft reconnaissance, ASCAT, and NOAA buoy 41049
indicate that Karen's circulation is becoming increasingly
elongated. A combination of data from these platforms also
supports maintaining an initial intensity of 40 kt for now. The
deterioration of Karen's structure suggests that weakening is
imminent, especially with an expected increase in northerly shear
during the next day or so. The GFS and ECMWF models--via their
simulated infrared satellite fields--are unanimous in showing Karen
losing its organized deep convection in about 36 hours. Based on
that, the new NHC forecast depicts Karen as becoming a remnant low
in 48 hours. Due to a significant increase in southwesterly shear
by day 4, the system is expected to open up into a surface trough by
day 5.
