MONTHLY WEATHER REVIEW
FIG. 6. GOES-12 visible satellite image of Hurricane Kate at 1745 UTC 4 Oct 2003. Maximum winds are estimated at 110 kt at the time of this image (courtesy of Naval Research Laboratory, Monterey, CA).
low nearly formed into a tropical depression before it moved west-northwestward over the northern Yucatan Peninsula on 29 September. On the next day, the low had crossed the Yucatan Peninsula into the southern Gulf of Mexico and merged with a stationary frontal boundary and its associated horizontal temperature gradient. High pressure over the northern Gulf of Mexico combined with the frontal low pressure system to produce gale-force winds over the central and south- ern Gulf of Mexico, including the Bay of Campeche. By 1 October, the gale center had drifted slowly west- ward into the Bay of Campeche and its convection be- came organized into curved band features. A recon- naissance flight indicated the horizontal temperature gradient had been replaced with warmer and homoge- neous tropical air. It is estimated that the extratropical gale center made the transition into Tropical Storm
Larry at 1800 UTC while centered about 260 n mi east- southeast of Tampico, Mexico.
Larry meandered slowly westward for two days and gradually strengthened. The cyclone reached its peak intensity of 55 kt at 0000 UTC 3 October about 160 n mi east-northeast of Vera Cruz, Mexico. Larry maintained that intensity for nearly three days while drifting errati- cally southward. Larry made landfall around 1000 UTC 5 October, near Paraiso in the state of Tabasco. By the next day, Larry weakened to a remnant low over the state of Vera Cruz. The remnant low moved southwest- ward and dissipated on 8 October over the eastern Pa- cific Ocean.
