A Hurricane Watch means that hurricane conditions are possible within the watch area, in this case within the next 24 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 100 AM CDT (0600 UTC), the center of Tropical Storm Dolores was located near latitude 16.4 North, longitude 102.9 West. Dolores is moving toward the northwest near 8 mph (15 km/h). A motion toward the northwest and then north-northwest at a increasing forward speed is expected tonight through early Sunday. On the forecast track, the center of Dolores is expected to cross the coast of southwestern or west-central Mexico within the warning area this afternoon. Dolores is then expected to move north-northwestward just inland of the west-central coast of Mexico through early Sunday. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Additional strengthening is expected until Dolores makes landfall this afternoon. Rapid weakening is forecast thereafter, and Dolores should dissipate inland by Sunday morning. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm Dolores can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP4, WMO header WTPZ44 KNHC, and on the web at www.hurricanes.gov/graphics_ep4.shtml?key_messages. WIND: Tropical storm conditions are expected to first reach the coast within the warning area later today, making outside preparations difficult or dangerous. Hurricane conditions are also possible within the hurricane watch area by this afternoon. 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 Dolores will affect portions of the southwestern coast of Mexico through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Tropical Storm Dolores Forecast Discussion Number 4
2021-06-19 04:42:17| National Hurricane Center (East Pacific)
Issued at 1000 PM CDT Fri Jun 18 2021 000 WTPZ44 KNHC 190242 TCDEP4 Tropical Storm Dolores Discussion Number 4 NWS National Hurricane Center Miami FL EP042021 1000 PM CDT Fri Jun 18 2021 Deep convection has been trying to consolidate closer to the estimated center of Dolores over the past several hours, suggesting that the broad circulation of the cyclone may be starting to contract. The CIMSS ADT and SATCON indicated some strengthening since the previous advisory, which justified increasing the storm's intensity to 45 kt for the 0000 UTC intermediate advisory. The recent Dvorak intensity estimates from both TAFB and SAB are in agreement with this value, and therefore 45 kt will be this advisory's initial intensity. Dolores is moving to the northwest at 8 kt around the periphery of a mid-level ridge to its east. A turn to the north-northwest along with a slight increase in forward speed is expected to occur through Sunday morning. There is about 120 n mi of spread in the track guidance at 24 h, and with the cyclone's angle of approach to the coast of Mexico, a variation in the track produces a large difference in the coastlines potentially affected by Dolores. The westernmost guidance has the center of the cyclone clipping the coast just north of Manzanillo in about 24 h, while the easternmost solutions make landfall in about 18 h near Punta San Telmo. Overall, the guidance has shifted little this evening, and therefore the latest NHC track forecast is very near the previous one, which lies near the various multi-model track consensus. This track would take the center of Dolores across the coast between Punta San Telmo and Manzanillo early Saturday afternoon. The surrounding environmental conditions are favorable for Dolores to continue to strengthen, with the main inhibiting factor being the broad circulation as indicated by an ASCAT overpass earlier this afternoon. Dolores is currently forecast to peak at an intensity of 55 kt by late Saturday morning before making landfall. How much the circulation consolidates over the next 12-18 h will likely determine if the peak intensity of Dolores prior to landfall is higher or lower than indicated. After landfall, Dolores should rapidly weaken over the rugged terrain of western Mexico, with the guidance in good agreement on dissipating the cyclone by Sunday morning. Other than indicating an earlier dissipation, the new NHC intensity forecast has changed little from the previous one. Key Messages: 1. Dolores is expected to continue strengthening tonight and early on Saturday, and it could be near hurricane strength when it reaches the coast of west-central Mexico by Saturday afternoon. A tropical storm warning and a hurricane watch are 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.
