SUMMARY OF 1000 PM CDT...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...21.3N 105.5W ABOUT 50 MI...85 KM NNW OF PUERTO VALLARTA MEXICO ABOUT 300 MI...485 KM ESE OF CABO SAN LUCAS MEXICO MAXIMUM SUSTAINED WINDS...75 MPH...120 KM/H PRESENT MOVEMENT...N OR 355 DEGREES AT 16 MPH...26 KM/H MINIMUM CENTRAL PRESSURE...984 MB...29.06 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: The government of Mexico has discontinued the Hurricane Warning from east of Playa Perula to Manzanillo and has issued a Tropical Storm Warning from north of Altata to Topolobampo. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Playa Perula to Altata Mexico A Hurricane Watch is in effect for... * North of Altata to Topolobampo Mexico A Tropical Storm Warning is in effect for... * North of Altata to Topolobampo Mexico A Tropical Storm Watch is in effect for... * Cabo San Lucas to La Paz Mexico A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere along the coasts of Sinaloa, Sonora, and Baja California Sur should monitor the progress of Nora. Additional watches and warnings may be required for portions of these areas tonight or on Sunday. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1000 PM CDT (0300 UTC), the center of Hurricane Nora was located near the coast of Mexico at latitude 21.3 North, longitude 105.5 West. Nora is moving toward the north near 16 mph (26 km/h). A turn toward the north-northwest is likely tonight or on Sunday, followed by a slower northwestward motion Sunday night through Tuesday. Nora is forecast to move roughly parallel to the coast of Mexico through early near week. However, even a small deviation to the right of the forecast track could cause Nora to move farther inland and dissipate. Maximum sustained winds have decreased to near 75 mph (120 km/h) with higher gusts. Little change in strength is forecast during the day or two if Nora's center stays over the waters of the Gulf of California. However, rapid weakening will likely occur if the center moves further inland. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 105 miles (165 km). The estimated minimum central pressure is 984 mb (29.06 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: Hurricane conditions are likely in portions of the southern hurricane warning area tonight and could spread northward through the warning area on Sunday. Tropical storm conditions are likely in the tropical storm warning area in mainland Mexico and are possible within the tropical storm watch area in Baja California Sur on Monday. RAINFALL: Nora is expected to produce rainfall totals of 8 to 12 inches with maximum amounts of 20 inches through early next week along the west coast of Mexico from the states of Michoacan northward to southern Sonora, including Baja California Sur. This rainfall will produce life-threatening flash flooding and mudslides. Toward the middle and latter part of next week, moisture associated with Nora may bring heavy rainfall to portions of the southwestern U.S. and central Rockies. STORM SURGE: A storm surge is expected to produce significant coastal flooding in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Nora are affecting the southern and southwestern coast of Mexico and will spread northward to the coast of Baja California Sur and into the Gulf of California into early next week. 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 AM CDT. Next complete advisory at 400 AM CDT. $$ Forecaster D. Zelinsky

Hurricane Ida Forecast Discussion Number 11
2021-08-29 04:50:24| National Hurricane Center (Atlantic)
Issued at 1000 PM CDT Sat Aug 28 2021 000 WTNT44 KNHC 290250 TCDAT4 Hurricane Ida Discussion Number 11 NWS National Hurricane Center Miami FL AL092021 1000 PM CDT Sat Aug 28 2021 The NOAA Hurricane Hunters investigated Ida earlier this evening and found that the maximum winds were still around 90 kt. Although the peak winds appear to have leveled off for now, the minimum pressure has continued to fall and was down to 966 mb at the last pass through the center an hour or two ago. In fact, the pressure has been dropping by about 2 mb per hour based on the aircraft data. In addition, tail Doppler Radar data from the aircraft indicate that the vortex has become more symmetric and that the inner core has contracted from the mission earlier today. These are signals that Ida is poised to strengthen further, and based on recent satellite images it appears that strengthening is imminent. Flight-level and SFMR observations also indicate that Ida's wind field has expanded and there is some indication of a double-wind maximum. The tropical-storm-force winds now extend outward up to 120 n mi from the center and hurricane-force winds up to 35 n mi from the eye. Ida continues to move steadily to the northwest at about 14 kt. There has been little change to the track forecast rationale. A subtropical ridge situated near the southeast U.S. coast is expected to shift westward during the next day or two. This feature should continue to steer Ida northwestward toward the Louisiana coast. The latest runs of the numerical models bring the center of Ida to southeast or south-central Louisiana Sunday afternoon. Although landfall is not expected for about 18 hours, impacts will begin well before that time. Tropical-storm-force winds are likely to begin overnight, therefore, all preparations to protect life and property must be rushed to completion. The new track forecast is just a little to the east of the previous one through landfall. After Ida moves inland, a turn to the north and then the northeast is expected as the storm moves in the flow on the northwest and north sides of the ridge. Ida remains over waters with high oceanic heat content, and in an atmospheric environment of low wind shear and abundant moisture. These conditions, combined with the improved structure of the hurricane, should allow Ida to rapidly intensify until it makes landfall. The models remain in fairly good agreement, and the NHC forecast holds steady and brings Ida to a dangerous major hurricane prior to landfall. After the storm moves inland on Sunday, rapid weakening is forecast due to a combination of land interaction, drier air and some increase in wind shear. Users are again reminded to not focus on the exact details of the track forecast as storm surge, wind, and rainfall impacts will extend far from the center. Rainfall impacts will also spread inland across the Lower Mississippi and Tennessee Valleys through early next week. Key Messages: 1. There is a danger of life-threatening storm surge inundation Sunday along the coasts of Louisiana, Mississippi, and Alabama within the Storm Surge Warning area. Extremely life-threatening inundation of 9 feet or greater above ground level is possible somewhere within the area from Morgan City, Louisiana, to the coast of Mississippi. Overtopping of local levees outside of the Hurricane and Storm Damage Risk Reduction System is possible where local inundation values may be higher. Interests throughout the warning area should follow any advice given by local officials. 2. Ida is expected to be an extremely dangerous major hurricane when it reaches the coast of Louisiana. Hurricane-force winds are expected Sunday in portions of the Hurricane Warning area along the Louisiana coast, including metropolitan New Orleans, with potentially catastrophic wind damage possible where the core of Ida moves onshore. Actions to protect life and property should be rushed to completion in the warning area. 3. Damaging winds, especially in gusts, will spread inland near the track of the center of Ida across portions of southeastern Louisiana and southwestern Mississippi Sunday night and early Monday. These winds will likely lead to widespread tree damage and power outages. 4. Ida is likely to produce heavy rainfall Sunday into Monday across the central Gulf Coast from southeast Louisiana, coastal Mississippi, and far southwestern Alabama, resulting in considerable to life-threatening flash and urban flooding and significant river flooding impacts. As Ida moves inland, significant flooding impacts are possible across portions of the Lower Mississippi, Tennessee, and Ohio Valleys through Wednesday.

Tropical Depression Eleven Forecast Discussion Number 1
2021-08-29 04:49:54| National Hurricane Center (Atlantic)
Issued at 1100 PM AST Sat Aug 28 2021 023 WTNT41 KNHC 290249 TCDAT1 Tropical Depression Eleven Discussion Number 1 NWS National Hurricane Center Miami FL AL112021 1100 PM AST Sat Aug 28 2021 Before sunset this evening, visible satellite images showed that a well-defined low level circulation was developing in association with the disturbance over the subtropical central Atlantic. However, up until a couple of hours ago, the system lacked sufficient organized deep convection to be considered a tropical cyclone by definition. Since that time, a deep convective burst has increased in size near, and to the east of the estimated center. In addition, a curved band has begun to develop over the southeastern portion of the circulation. Based on this increase in convective organization, advisories are being initiated on Tropical Depression Eleven. There was no ASCAT data this evening over the cyclone, so the initial intensity of 30 kt is based on the latest Dvorak CI number from TAFB. The initial motion of the depression is 050/10 kt. The cyclone is embedded in southwesterly flow to the southeast of a mid- to upper-level trough and an associated cold front. This flow is forecast to increase as the cold front approaches the cyclone, resulting in the system accelerating northeastward over the next day or so. Once the cyclone interacts with this frontal boundary in a couple of days, a turn to the north is expected. The model guidance is in very good agreement on this scenario, and the NHC track forecast lies in the middle of the consensus tracks. Baroclinic forcing and upper-level diffluence should aid in intensifying the depression over the next 24 h, despite increasing shear. By 36 h, the combination of interaction with the cold front and passage over much cooler waters should result in extratropical transition. The system is then forecast to become absorbed by a larger low pressure system by midweek. The NHC intensity forecast is near the various multi-model consensus solutions.
