2021-09-22 13:59:03| National Hurricane Center (Atlantic)

000 ABNT20 KNHC 221158 CCA TWOAT Tropical Weather Outlook...Corrected NWS National Hurricane Center Miami FL 800 AM EDT Wed Sep 22 2021 Corrected location of Peter relative to Puerto Rico. For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Depression Peter, located a few hundred miles north of Puerto Rico, and on Tropical Depression Rose, located about 1000 miles west-northwest of the Cabo Verde Islands. Showers and thunderstorms continue to become better organized in association with a tropical wave located several hundred miles southwest of the Cabo Verde Islands. Environmental conditions are expected to remain conducive for additional development, and a tropical depression is expected to form within a day or two while the system moves westward at 10 to 15 mph across the eastern and central tropical Atlantic Ocean. Additional information on this system, including gale warnings, can be found in High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...high...90 percent. * Formation chance through 5 days...high...90 percent. A gale-force, non-tropical low pressure system, the remnants of Odette, is located a little less than 500 miles west-northwest of the westernmost Azores. This low could acquire some subtropical characteristics over marginally warm waters during the next few days while it makes a counter-clockwise loop over the north-central Atlantic Ocean. However, by the weekend, this system is expected to move into an environment of strong upper-level winds. Additional information on this system, including gale warnings, can be found in High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...medium...50 percent. && High Seas Forecasts issued by the National Weather Service can be found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php $$ Forecaster Papin

000 ABPZ20 KNHC 221141 TWOEP Tropical Weather Outlook NWS National Hurricane Center Miami FL 500 AM PDT Wed Sep 22 2021 For the eastern North Pacific...east of 140 degrees west longitude: A broad and elongated area of low pressure located several hundred miles southwest of the southern tip of the Baja California peninsula continues to produce disorganized showers and thunderstorms. Environmental conditions are somewhat conducive for development, and a short-lived tropical depression could form on Thursday or Friday while the low moves generally northwestward at 10 to 15 mph. This system is forecast to move over cooler waters and into an environment of stable air and strong upper-level winds this weekend, which should inhibit further development. * Formation chance through 48 hours...medium...40 percent. * Formation chance through 5 days...medium...50 percent. $$ Forecaster Beven

Tropical Depression Peter Forecast Discussion Number 15

2021-09-22 10:40:30| National Hurricane Center (Atlantic)

Issued at 500 AM AST Wed Sep 22 2021 000 WTNT41 KNHC 220840 TCDAT1 Tropical Depression Peter Discussion Number 15 NWS National Hurricane Center Miami FL AL162021 500 AM AST Wed Sep 22 2021 Peter is a disorganized tropical depression. The low-level center is fully exposed and currently located a couple of hundred miles north of Puerto Rico. Most of the associated thunderstorm activity remains displaced well east of the center due to about 30 kt of westerly shear. The initial intensity is held at 30 kt based on a 0206 UTC ASCAT-B pass that showed a swath of 25-30 kt winds about 60 n mi north of the center. The ASCAT data also showed that the circulation has become quite elongated. Since the hostile conditions of strong westerly shear and dry air entrainment are not expected to let up, a continued gradual decay of Peter is forecast. The system is still predicted to become a remnant low in 36 hours and dissipate in a few days, but both of these could occur sooner. The depression is moving northwestward, with the latest initial motion estimated to be 310/10 kt. The cyclone is expected to turn northward by tonight and then northeastward by the end of the week as the system moves in the flow on the east side of a deep-layer trough. The NHC track forecast is a little to the east of the previous one and close to an average of the GFS and ECMWF models. Key Messages: 1. Rainfall around the southern periphery of Peter may lead to areas of urban and small stream flooding through Thursday morning across northern Hispaniola, Puerto Rico, and portions of the Virgin Islands.
