Interests along the southern coast of Mexico should monitor the progress of the depression. DISCUSSION AND OUTLOOK ---------------------- At 400 PM CDT (2100 UTC), the center of Tropical Storm Vicente was located near latitude 13.3 North, longitude 92.2 West. Vicente is moving slowly toward the northwest near 2 mph (4 km/h). A turn toward the west and west-southwest, with some increase in forward speed, is expected through the weekend. On the forecast track, the center of Vicente should gradually move away from the coasts of Guatemala and southeastern Mexico. Maximum sustained winds have increased to near 40 mph (65 km/h) with higher gusts. Additional strengthening is forecast during the next couple of days. Vicente is a small tropical storm, and tropical-storm-force winds extend outward up to 35 miles (55 km) from the center. The estimated minimum central pressure is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Through Wednesday morning, Vicente is expected to produce 5 to 10 inches of rain with local amounts to 15 inches across portions of El Salvador and southern Guatemala, with 3 to 6 inches and local amounts to 10 inches near the Pacific coast of southeastern Mexico. This rainfall could produce life-threatening flash flooding and landslides within mountainous terrain. NEXT ADVISORY ------------- Next complete advisory at 1000 PM CDT. $$ Forecaster Berg ]]>

  • Tropical Storm Vicente Forecast Discussion Number 2
    Issued at 400 PM CDT Fri Oct 19 2018 000 WTPZ43 KNHC 192036 TCDEP3 Tropical Storm Vicente Discussion Number 2 NWS National Hurricane Center Miami FL EP232018 400 PM CDT Fri Oct 19 2018 Although tiny, the cyclone continues to display well-defined convective banding. The system's quick formation and small size make it difficult to have high confidence in its current intensity, and the various subjective and objective estimates range from T1.8/28 kt from the ADT to T3.0/45 kt from SAB. As a compromise, the intensity is set at 35 kt, which is closest to the TAFB estimate and the most recent SATCON number, and the depression is upgraded to Tropical Storm Vicente. As noted this morning, warm waters and low shear should induce further strengthening during the next 48 hours. On one hand, this intensification could be more than what is being indicated by the models, since small systems can have a tendency to gain strength quickly. On the other hand, Vicente will be interacting with a Gulf of Tehuantepec gap wind event during the next 48 hours, and the storm could end up ingesting some drier, more stable air into its circulation. The NHC intensity forecast favors the former scenario and is a little above the guidance envelope for the first 2-3 days. After day 3, an increase in shear, interaction with another possible tropical cyclone to the west, and possible interaction with land could all conspire to arrest the intensification trend, and weakening is expected by the end of the forecast period. It is also possible that Vicente could dissipate before the end of the 5-day period. This scenario is reminiscent of, and has similarities to, the interaction of Tropical Storm Ileana and Hurricane John back in early August. Vicente is moving very slowly northwestward, or 305/2 kt. The track models are indicating that the ongoing gap winds over the Gulf of Tehuantepec may have a greater influence of Vicente than previously thought, forcing the storm to turn west-southwestward in the next 24-48 hours. After 48 hours, Vicente should gradually enter the flow between mid-level ridging over Mexico and low pressure west of Mexico, causing it to turn back to the west and northwest on days 3 through 5. The new NHC track forecast is not too different from the morning forecast during that period, and it's closest to the paths shown by the GFS, HCCA, and FSSE guidance, which would bring the center close to the coast of Mexico later in the forecast period. There are considerable speed differences, however, and the NHC forecast splits the difference between the fast ECMWF solution and the slow GFS scenario. Even though Vicente should begin to slowly pull away from the coast tonight and on Saturday, heavy rainfall, with possible life-threatening flash flooding, is expected over portions of El Salvador, Guatemala, and southeastern Mexico during the next few days.
