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 complete. A Hurricane Watch means that hurricane conditions are possible within the watch area. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. Interests elsewhere in Haiti, the Dominican Republic, Cuba, the southeastern and central Bahamas, and the Turks and Caicos Islands, and Bermuda should monitor the progress of Melissa. Additional watches and warnings could be required later today. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 200 PM EDT (1800 UTC), the eye of Hurricane Melissa was located by Air Force Reserve Hurricane Hunter aircraft near latitude 16.4 North, longitude 76.9 West. Melissa is moving toward the west near 5 mph (7 km/h). A slow westward motion is expected today, followed by a turn to the north and northeast on Monday and Tuesday. On the forecast track, the core of Melissa is expected to move near or over Jamaica on Tuesday, across southeastern Cuba Tuesday night, and across the southeastern Bahamas on Wednesday. Maximum sustained winds are near 140 mph (220 km/h) with higher gusts. Melissa is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Additional intensification is forecast over the next day or so, followed by fluctuations in intensity. Melissa is expected to be a powerful major hurricane when making landfall in Jamaica Monday night or Tuesday morning and southeastern Cuba late Tuesday. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The minimum central pressure estimated by aircraft dropsonde data is 946 mb (27.94 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Melissa can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC. WIND: Tropical storm conditions are likely occuring in Jamaica, with hurricane conditions expected to begin by Monday. Tropical storm conditions are expected in the warning area in Haiti today. The potential for hurricane conditions in the watch area in Haiti have diminished for today, but there is still a possibility of hurricane conditions occurring there on Tuesday. Hurricane conditions are possible in the watch area in eastern Cuba on Tuesday into Wednesday. RAINFALL: Melissa is expected to bring storm total rainfall of 15 to 30 inches to portions of southern Hispaniola and Jamaica through Wednesday, with local maxima of 40 inches possible. Catastrophic flash flooding and numerous landslides are likely. For eastern Cuba, total rainfall of 10 to 15 inches, with local amounts to 20 inches, is expected by Tuesday into Wednesday resulting in life-threatening flash flooding and numerous landslides. Over the Southeast Bahamas, total rainfall of 4 to 8 inches is expected Tuesday into Wednesday resulting in areas of flash flooding. Over the Turks and Caicos, total rainfall of 1 to 4 inches is expected Tuesday into Wednesday. For a complete depiction of forecast rainfall associated with Melissa, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at3.shtml?rainqpf STORM SURGE: Life-threatening storm surge is likely along the south coast of Jamaica late Monday through Tuesday morning. Peak storm surge heights could reach 9 to 13 feet above ground level, near and to the east of where the center of Melissa makes landfall. This storm surge will be accompanied by large and destructive waves. There is a potential for significant storm surge along the southeast coast of Cuba late Tuesday or Wednesday. SURF: Swells generated by Melissa are expected to affect portions of Hispaniola, Jamaica, eastern Cuba, and the Cayman Islands during the next several days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Hurricane Melissa Forecast Discussion Number 21
Issued at 1100 AM EDT Sun Oct 26 2025 000 WTNT43 KNHC 261459 TCDAT3 Hurricane Melissa Discussion Number 21 NWS National Hurricane Center Miami FL AL132025 1100 AM EDT Sun Oct 26 2025 After rapidly intensifying over the past day or so, NOAA-P3 aircraft data indicates that Melissa's intensity has leveled off this morning. Melissa remains a very formidable hurricane on satellite imagery, with a clearing eye quite evident on morning visible imagery, and the eye temperature has warmed to +15-20C. Meanwhile the eyewall convection continues to remain robust with cloud tops as low as -75 to -80C encircling the core. With that said, the eye presentation from the Kingston, Jamaica radar is not as pristine, with the eyewall occasionally open on the east side, and some evidence of concentric bands forming off and on. Zooming out a bit, there still remains some evidence of light to moderate westerly shear undercutting the expanding storm outflow, and Melissa’s primarily rainbands are distributed mostly on the eastern side of the circulation. NOAA-P3 aircraft data this morning had a peak 700- mb flight level wind of 120 kt, and Tail Doppler Radar (TDR) wind retrievals were up to 129 kt at 0.5 km, and 129 kt in the 500 m average of a dropsonde launched in the north eyewall. While this data would support a somewhat lower intensity, the subjective and objective satellite based intensity estimates are mostly higher, ranging from 115 to 140 kt. The initial intensity will be held at 120 kt, on the lower end of those estimates, and this value could be a little generous based on the aircraft data. The major hurricane is moving westward this morning, from aircraft fixes estimated at 270/3 kt. This motion is expected to continue for the next 24-36 h as a narrow mid-level ridge to the north of Melissa imparts the majority of the steering. Thereafter, a short-wave trough moving into the southeastern United States is expected to erode this ridge, allowing Melissa to turn sharply to the northeast, with gradual acceleration. On the forecast track, Melissa's core is expected to be near the Jamaica coastline by Tuesday morning, moving across the island and then approaching and moving over eastern Cuba by Tuesday night. While the track guidance has become tightly clustered over the first 24-48 hours, the along-track spread starts to increase significantly after that time period, with Google DeepMind ensemble solutions on Wednesday morning ranging from between Jamaica and eastern Cuba in the Caribbean Sea, over eastern Cuba, or in the Southwestern Atlantic near the Southeastern Bahamas and Turks and Cacaos Islands. The latest NHC track forecast was nudged just a little westward of the prior track, once again blending the reliable track aids HFIP Corrected Consensus Approach (HCCA), and Google DeepMind ensemble mean (GDMI). It is unclear if the current pause in Melissa's intensification is temporary. While there have not been obvious indications of a secondary eyewall formation yet, there are some concentric reflectivity bands appearing on both Jamaica and NOAA-P3 TDR data occasionally, though the inner eyewall remains strong. Some of the guidance this morning has actually increased from yesterday at this time, and notably both the HAFS-A/B explicitly forecast a Category 5 hurricane shortly before they show landfall in Jamaica. The latest NHC intensity forecast will continue to show a peak intensity of 140 kt. However, inner-core fluctuations like eyewall replacement cycles could occur at any time. Regardless, Melissa is forecast to reach Jamaica as an upper-end category 4 hurricane, which will only exacerbate any damages caused by heavy rainfall and flooding over the next 2 days. Melissa will likely weaken some as it traverses over the higher terrain of Jamaica, but it is still forecast to be a major hurricane when it subsequently moves over eastern Cuba in 60-72 hours. Thereafter, increasing southwesterly shear should cause gradual weakening, but Melissa could still be near hurricane intensity when it makes it closest approach to Bermuda in about 5 days. The latest NHC intensity forecast is on the high end of the intensity guidance, but not far off the GDMI, and HAFS-A/B intensity aids. Key Messages: 1. Jamaica: Seek shelter now. Damaging winds and heavy rainfall today and Monday will cause catastrophic and life-threatening flash flooding and numerous landslides before potentially devastating winds arrive Monday night and Tuesday morning. Extensive infrastructural damage, long-duration power and communication outages, and isolation of communities are expected. Life-threatening storm surge is likely along portions of the southern coast Monday night and Tuesday morning. 2. Haiti: Catastrophic and life-threatening flash flooding and landslides are expected across southwestern Haiti through midweek, likely causing extensive infrastructural damage and isolation of communities. Although winds are temporarily decreasing on the Tiburon peninsula, they could increase again across much of western Haiti on Tuesday. 3. Dominican Republic: Heavy rainfall through midweek could produce catastrophic flash flooding and numerous landslides in southern portions of the country. 4. Eastern Cuba, Southeast Bahamas, and the Turks and Caicos: Monitor Melissa closely. There is an increasing risk of a significant storm surge, damaging winds, and heavy rainfall Tuesday and Wednesday. In eastern Cuba, the risk of life-threatening flash flooding and landslides is increasing. A Hurricane Watch is in effect for portions of eastern Cuba.

Tropical Storm Sonia Forecast Discussion Number 8
Issued at 800 AM PDT Sun Oct 26 2025 000 WTPZ43 KNHC 261446 TCDEP3 Tropical Storm Sonia Discussion Number 8 NWS National Hurricane Center Miami FL EP182025 800 AM PDT Sun Oct 26 2025 Deep convection returned over the low-level center overnight, but over the last several hours satellite imagery shows the convective structure has become a little more broken. The low-level center is likely situated on the southern end of the convective shield due to southerly wind shear. The latest subjective satellite intensity estimates were both data-T 3.0 from both TAFB and SAB. The objective intensity estimates from UW-CIMSS range from 35 to 50 kt. Using these estimates, the initial intensity will be held at 45 kt for this advisory. Sonia is moving slowly westward at an estimated motion of 280/03 kt. The system seems to be gradually turning towards the west-northwest towards a weakness in the subtropical ridge, with a continued slow forward motion the next day or so. As the system begins to weaken and become a more shallow vortex, the system should turn back toward the west within the low-level wind flow at a sightly faster forward speed. The latest NHC forecast is slightly near the previous and lies between the corrected consensus HCCA and Google DeepMind solutions. The storm will continue to deal with moderate wind shear, but will remain over warm sea surface temperatures for another day or so. Thus, little change in intensity is forecast, with the potential for some slight strengthening today. Beyond the 24-36 h time period, a weakening trend is forecast due to an increase in wind shear, and sea surface temperatures cooling along the forecast track. Water vapor satellite imagery shows abundant dry air to the west of the system and mid-level RH values drop into the 40 percent range in 2 to 3 days. The combination of dry air and shear should cause the system to gradually lose convection, and become a remnant low by 60 hours. This forecast is in good agreement with the global model simulated IR satellite solutions, and the latest NHC intensity forecast follows these trends, with the remnant low dissipating by the end of the forecast period.
