  • Eastern North Pacific Tropical Weather Outlook

    000 ABPZ20 KNHC 231105 TWOEP Tropical Weather Outlook NWS National Hurricane Center Miami FL 500 AM PDT Mon Sep 23 2019 For the eastern North Pacific...east of 140 degrees west longitude: The National Hurricane Center is issuing advisories on Tropical Depression Mario, located a a little more than 100 miles west of the southwestern coast of the Baja California peninsula, and on Tropical Storm Kiko, located over the far southwestern part of the basin. A small low pressure system located several hundred miles south of the southwestern coast of Mexico is producing disorganized showers and thunderstorms. This system is expected to drift northward or northwestward during the next few days, and significant development is unlikely due to strong upper-level winds. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. $$ Forecaster Zelinsky

  • Tropical Storm Kiko Forecast Discussion Number 44

    Issued at 1100 PM HST Sun Sep 22 2019 000 WTPZ43 KNHC 230859 TCDEP3 Tropical Storm Kiko Discussion Number 44 NWS National Hurricane Center Miami FL EP132019 1100 PM HST Sun Sep 22 2019 GOES-17 enhance infrared imagery and an earlier METOP-A AMSU pass show that resilient Kiko is producing intermittent bursts of deep convection with associated -77C cold cloud tops near the surface center. These convective bursts, based on the TAFB and SAB intensity estimates, are substantial enough to maintain its tropical storm status of 35 kt for this advisory. Both the ECMWF and FV3GFS Decay SHIPS statistical-dynamical intensity models show Kiko briefly re-strengthening as it continues moving over warm SSTs and in a favorable upper-level wind environment. By Tuesday afternoon, increasing southwesterly shear and cooler waters should induce a weakening trend, and Kiko is forecast to become a remnant low in less than 3 days with dissipation occuring by the end of the forecast period. The initial motion is estimated to be west-southwestward, or 255/8 kt, just south of due west. Kiko is expected to turn westward to west-northwestward on Monday, and then northwestward on Tuesday as a high amplitude mid-tropospheric trough cuts off, from the upper-level westerlies, to the northwest of the cyclone. At the 72 hour period, as the cyclone degenerates into a vertically shallow remnant low, Kiko should, once again, turn back toward the southwest within the low-level tradewind flow. The NHC track forecast is close to the previous advisory and based on a blend of the various multi-model consensus aids.
