Tropical Storm Dolores Public Advisory Number 2
2021-06-18 16:49:51| National Hurricane Center (East Pacific)
Issued at 1000 AM CDT Fri Jun 18 2021 000 WTPZ34 KNHC 181449 TCPEP4 BULLETIN Tropical Storm Dolores Advisory Number 2 NWS National Hurricane Center Miami FL EP042021 1000 AM CDT Fri Jun 18 2021 ...DEPRESSION STRENGTHENS TO TROPICAL STORM DOLORES... ...TROPICAL STORM WARNING AND HURRICANE WATCH ISSUED FOR A PORTION OF THE WEST-CENTRAL COAST OF MEXICO... SUMMARY OF 1000 AM CDT...1500 UTC...INFORMATION ----------------------------------------------- LOCATION...14.7N 102.5W ABOUT 230 MI...370 KM S OF LAZARO CARDENAS MEXICO ABOUT 320 MI...515 KM SSE OF MANZANILLO MEXICO MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...WNW OR 285 DEGREES AT 10 MPH...17 KM/H MINIMUM CENTRAL PRESSURE...1004 MB...29.65 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: The government of Mexico has issued a Tropical Storm Warning from Lazaro Cardenas to Cabo Corrientes and a Hurricane Watch from Punta San Telmo to Cabo Corrientes. A Tropical Storm Watch has also been issued north of Cabo Corrientes to Escuinapa. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Lazaro Cardenas to Cabo Corrientes Mexico A Hurricane Watch is in effect for... * Punta San Telmo to Cabo Corrientes Mexico A Tropical Storm Watch is in effect for... * North of Cabo Corrientes to Escuinapa Mexico A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 24 to 36 hours. A Hurricane Watch means that hurricane conditions are possible within the watch area, in this case within the next 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1000 AM CDT (1500 UTC), the center of Tropical Storm Dolores was located near latitude 14.7 North, longitude 102.5 West. Dolores is moving toward the west-northwest near 10 mph (17 km/h). A turn toward the northwest is expected later today, followed by a turn toward the north-northwest and north with an increase in forward speed Saturday and Saturday night. On the forecast track, the center of Dolores is expected to cross the coast of west-central Mexico within the warning area Saturday evening. Dolores is then expected to move northward along the west-central coast of Mexico and then inland over northwestern Mexico Saturday night and Sunday. Maximum sustained winds have increased to near 40 mph (65 km/h) with higher gusts. Additional strengthening is forecast, and Dolores could be near hurricane strength when it reaches the coast of west-central Mexico by Saturday evening. Weakening is expected Saturday night and Sunday while Dolores moves northward near and along the west-central coast of Mexico. Tropical-storm-force winds extend outward up to 35 miles (55 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to first reach the coast within the warning area Saturday afternoon, making outside preparations difficult or dangerous. Hurricane conditions are also possible within the hurricane watch area by late Saturday. Tropical storm conditions are possible within the tropical storm watch area Saturday night into Sunday morning. RAINFALL: Dolores will produce heavy rains over coastal sections of the Mexican states of Oaxaca, Guerrero, Michoacan, Colima, Jalisco, and Nayarit during the next few days, with rainfall totals of 6 to 10 inches expected with isolated maximum amounts of 15 inches possible. As a result, life-threatening flash flooding and mudslides may occur. STORM SURGE: A storm surge is expected to produce coastal flooding near and to the east of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by the depression will affect portions of the southwestern coast of Mexico during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 100 PM CDT. Next complete advisory at 400 PM CDT. $$ Forecaster Berg

Tropical Storm Dolores Forecast Discussion Number 2
2021-06-18 16:49:46| National Hurricane Center (East Pacific)
Issued at 1000 AM CDT Fri Jun 18 2021 464 WTPZ44 KNHC 181449 TCDEP4 Tropical Storm Dolores Discussion Number 2 NWS National Hurricane Center Miami FL EP042021 1000 AM CDT Fri Jun 18 2021 Recent SSMIS microwave imagery indicates that convective banding continues to become established to the north and west of the cyclone's center, while the overall area of deep convection is gradually expanding. Dvorak satellite classifications have increased to T2.0/30 kt from TAFB and T2.3/35 kt from SAB, and the depression is therefore being upgraded to a tropical storm with maximum winds of 35 kt. Dolores is moving toward the west-northwest (285/9 kt), to the south of a weak mid-level ridge which extends from the northwestern Caribbean Sea to central Mexico. Since Dolores is now reaching the western extent of this ridge, the storm is expected to turn northwestward and then north-northwestward around the ridge later today and into Saturday, reaching the coast of Colima or Jalisco by Saturday evening. The track models agree on this general scenario, although there is some spread on exactly where and if the center makes landfall. The GFS and HWRF models show a sharper turn toward the north, with the center moving inland near or south of the Manzanillo area, while the ECMWF and UKMET models depict a wider sweeping turn, keeping the center near or just off the coast in the vicinity of Cabo Corrientes. The updated NHC track forecast is between these two scenarios, near the TVCE and HCCA consensus aids, depicting a potential landfall along the Colima or Jalisco coasts Saturday evening. The new NHC track forecast is not too different than the previous forecast, although it does show Dolores reaching the coast a little sooner than previously expected. Additional strengthening is anticipated up until Dolores's potential landfall due to very warm sea surface temperatures (29 to 30 degrees Celsius), a moist environment, and significant upper-level divergence. The intensity models agree on this strengthening, although since several of the track models already have Dolores inland by 36 hours (which the NHC official forecast does not), they're showing the cyclone's intensity too low at that time. The NHC intensity forecast is close to the HCCA consensus aid through 24 hours, but then it is above all of the guidance at 36 hours in order to show at least some additional strengthening before Dolores reaches the coast. Based on this forecast, Dolores is expected to be near or just below hurricane strength when it reaches the coast. This new forecast necessitates the issuance of a tropical storm warning and a hurricane watch for a portion of the west-central coast of Mexico. Depending on the amount of land interaction after 36 hours, Dolores is expected to weaken fast as it continues moving northward along the west-central coast of Mexico. Key Messages: 1. Dolores is expected to continue strengthening today and on Saturday, and it could be near hurricane strength when it reaches the coast of west-central Mexico by Saturday evening. A tropical storm warning and a hurricane watch are now in effect for portions of the southwestern and west-central coasts of Mexico. 2. Heavy rains are forecast over coastal sections of the Mexican states of Oaxaca, Guerrero, Michoacan, Colima, Jalisco, and Nayarit during the next few days, which could result in life-threatening flash flooding and mudslides.
