Issued at 600 PM MDT Sun Aug 29 2021 000 WTPZ34 KNHC 292346 TCPEP4 BULLETIN Tropical Storm Nora Intermediate Advisory Number 17A NWS National Hurricane Center Miami FL EP142021 600 PM MDT Sun Aug 29 2021 ...HEAVY RAINS WITH THE RISK OF FLOODING CONTINUES NEAR NORA ALONG PORTIONS OF THE NORTHWEST COAST OF MEXICO...

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Mazatlan to Topolobampo Mexico A Tropical Storm Watch is in effect for... * North of Topolobampo to Huatabampito Mexico A Tropical Storm Warning means that tropical storm conditions are expected or occurring somewhere within the warning area. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within the next 12 to 24 hours. Interests elsewhere along the coast of Sonora should monitor the progress of Nora. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 600 PM MDT (0000 UTC), the center of Tropical Storm Nora was located along the coast of Mexico, near latitude 24.5 North, longitude 107.7 West. Nora is moving toward the north-northwest near 12 mph (19 km/h). A northwestward motion at a slightly slower forward speed is expected to begin tonight and continue through early this week. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. At least gradual weakening is forecast during the next couple of days as the center moves roughly parallel to the coast of Mexico. However, rapid weakening will likely occur if the center moves inland sooner than forecast. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 992 mb (29.30 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Nora can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP4, WMO header WTPZ44 KNHC, and on the web at hurricanes.gov/graphics_ep4.shtml?key_messages. WIND: Tropical storm conditions are ongoing in portions of the Tropical Storm Warning area in mainland Mexico. Tropical storm conditions are possible within the Tropical Storm Watch area on Monday. RAINFALL: Heavy rainfall is likely along the west coast of Mexico from Jalisco to Sonora through late week as Nora lifts northward through the Gulf of California. Rainfall of 8 to 12 inches with maximum amounts of 20 inches is possible. This rainfall will produce life-threatening flash flooding and mudslides. Rainfall of 2 to 4 inches with maximum amounts of 6 inches is possible in Baja California Sur. Toward the middle and latter part of the week, moisture associated with Nora is likely to bring heavy rainfall and the potential for scattered flash flooding to portions of the southwestern U.S. and central Rockies. STORM SURGE: A storm surge is expected to produce coastal flooding in areas of onshore winds within the tropical storm warning area. Near the coast, the surge will be accompanied by large waves. SURF: Swells generated by Nora are affecting the southwestern coast of Mexico and will spread northward into the Gulf of California through Monday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 900 PM MDT. $$ Forecaster D. Zelinsky

Tropical Storm Nora Forecast Discussion Number 17
2021-08-29 22:52:12| National Hurricane Center (East Pacific)
Issued at 300 PM MDT Sun Aug 29 2021 000 WTPZ44 KNHC 292052 TCDEP4 Tropical Storm Nora Discussion Number 17 NWS National Hurricane Center Miami FL EP142021 300 PM MDT Sun Aug 29 2021 Visible satellite imagery and surface observations along the west-central coast of Mexico suggest that the center of Nora has re-formed closer to a mass of deep convection that has persisted today over the southern Gulf of California. Various satellite data sets indicate that Nora is weakening. The latest SSMIS microwave data reveal that the structure of Nora has degraded since this morning, especially in the mid-levels where an eyewall structure is no longer evident. Additionally, a 15 UTC ASCAT-A pass shows the winds are substantially weaker than previously estimated. Thus, the initial intensity has been lowered to 50 kt for this advisory. The initial motion is somewhat uncertain given the earlier center relocation, but it is estimated to be north-northwestward, or 330/10 kt. The global models suggest the tropical cyclone will move generally northwestward over the next couple of days, between an upper-level low offshore the Baja California peninsula and a mid-level ridge to the east of Nora. This motion should keep the center of Nora along the coast, or just inland over mainland west-central or northwestern Mexico. The official NHC track forecast is once again shifted a little to the right based on the latest track guidance, which brings the cyclone further inland by Tuesday. Nora is forecast to gradually weaken over the next few days as the system continues to interact with the coastline of Mexico. Despite warm SSTs in the Gulf of California and weak environmental shear, it appears unlikely that Nora will move far enough away from the coast to take advantage of this favorable environment. In fact, it is certainly plausible that the center of Nora could move well inland earlier than forecast and weaken more rapidly. The NHC intensity forecast has been adjusted about 10 kt weaker at all forecast hours based on today's data supporting a much weaker initial intensity. Key Messages: 1. Nora is forecast to be at or near tropical storm strength while it moves near the coast of Sinaloa and southern Sonora through early Tuesday, and tropical storm warnings and watches are in effect for portions of that coastline. Interests in these areas should closely monitor the progress of Nora. 2. Heavy rain associated with Nora is expected across the west coast of Mexico from the states of Colima northward to southern Sonora. This rain will likely result in life-threatening flash flooding and mudslides across these regions. Rainfall from Nora is likely to spread into the southwestern U.S. and central Rockies during the middle to latter portion of the week bringing the potential for flash flooding to the region.
