For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 300 AM CST (0900 UTC), the center of Tropical Storm Boris was located near latitude 16.4 North, longitude 98.4 West. Boris is moving toward the north-northwest near 6 mph (9 km/h). A turn toward the northwest and an increase in forward speed is expected early this morning. On the forecast track, the center of Boris will move farther inland over eastern Guerrero this morning. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Rapid weakening is expected, and Boris is forecast to dissipate this afternoon. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure is 1003 mb (29.62 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Boris can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP2 and WMO header WTPZ42 KNHC. RAINFALL: Boris is expected to produce additional rainfall totals of 1 to 4 inches across coastal portions of the Mexican states of Guerrero and Oaxaca today. Some risk of additional flooding and mudslides continues this morning, especially in areas of steep terrain. For a complete depiction of forecast rainfall associated with Tropical Storm Boris, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_ep2.shtml?rainqpf WIND: Tropical storm conditions are likely occurring along the coast in the warning area and will continue through early this morning.

Tropical Storm Boris Forecast Discussion Number 9
Issued at 300 AM CST Tue Jun 09 2026 000 WTPZ42 KNHC 090842 TCDEP2 Tropical Storm Boris Discussion Number 9 NWS National Hurricane Center Miami FL EP022026 300 AM CST Tue Jun 09 2026 Organized convection associated with Boris began falling apart about 12 hours ago, and now there is barely any organized convection remaining. It is quite difficult to estimate where the low-level center is, and there have been no recent microwave images, scatterometer data, or nearby surface observations. Based on the GOES proxy vis imagery, it is estimated that the center of Boris has moved inland along the border of Oaxaca and Guerrero. The initial intensity has been brought down to 35 kt which could be generous, and is in good agreement with a blend of the latest subjective and objective satellite intensity estimates. The current motion is estimated to be north-northwest at 5 kt. A turn to the northwest is expected shortly as a mid-level ridge builds over the western Gulf of America, and little change has been made to the NHC track forecast. Model guidance is in good agreement showing rapid weakening and dissipation occurring over land very soon. The NHC forecast indicates weakening to a remnant low by midday today with dissipation by hour 24, although it is possible that Boris could dissipate sooner. The threat of heavy rainfall continues to be the primary hazard of concern with this slow-moving system, which will likely result in flash flooding and mudslides in mountainous terrain through this morning. Key Messages: 1. Heavy rainfall associated with Tropical Storm Boris across portions of southern Mexico will subside by later today. Some risk of additional flooding and mudslides continues this morning, especially in areas of steep terrain. 2. Tropical storm conditions are likely occurring along the coast within the Tropical Storm Warning area and will continue through early this morning.

For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 300 AM CST (0900 UTC), the center of Tropical Storm Cristina was located near latitude 12.7 North, longitude 87.6 West. Cristina is moving toward the north-northeast near 3 mph (6 km/h). The storm is forecast to meander near the coast today before turning toward the northwest and west-northwest through midweek.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Little change in strength is forecast today, followed by some weakening through midweek. Tropical-storm-force winds extend outward up to 80 miles (130 km), mainly to the south of the center. The estimated minimum central pressure is 1006 mb (29.71 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Cristina can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP3 and WMO header WTPZ43 KNHC. RAINFALL: Cristina is expected to produce rainfall totals of 4 to 8 inches, with maximum totals of 12 inches possible across coastal portions of Nicaragua, Honduras, El Salvador, and Guatemala through Thursday morning. This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain. For a complete depiction of forecast rainfall associated with Cristina, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_ep3.shtml?rainqpf STORM SURGE: Coastal flooding from storm surge is possible in areas of onshore winds. Near the coast, the surge will be accompanied by large and damaging waves. WIND: Tropical storm conditions are expected to spread along portions of the coast within the warning area today.

Tropical Storm Cristina Forecast Discussion Number 5
Issued at 300 AM CST Tue Jun 09 2026 000 WTPZ43 KNHC 090842 TCDEP3 Tropical Storm Cristina Discussion Number 5 NWS National Hurricane Center Miami FL EP032026 300 AM CST Tue Jun 09 2026 Strong northerly shear has exposed the low-level center of Cristina in overnight shortwave-IR satellite images. The remaining convective activity is confined to the southern portion of the circulation, where scatterometer data from around 0230 UTC indicated that tropical-storm-force winds were still occurring. While there were several 35-kt wind vectors from those ASCAT passes, the satellite presentation of the storm has notably deteriorated since that time. The initial intensity is lowered to 35 kt for this advisory, consistent with the latest UW-CIMSS objective (30-37 kt) and TAFB subjective (35 kt) satellite intensity estimates. The long-term motion of Cristina is north-northeastward (020/3 kt). However, the exposed center has wobbled around overnight and now lies very near the coast of northwestern Nicaragua. There is more spread in the near-term track guidance than usual, with models struggling to initialize the center of Cristina in the proper location. The future track is uncertain and depends on whether the circulation remains intact while it meanders near the coast of northwestern Nicaragua and southern Honduras today. If the center remains offshore, then most models eventually agree on a slow westward to northwestward motion that takes Cristina toward El Salvador on Wednesday. The updated track forecast lies to the right of the previous prediction and the latest model consensus given the storm's current location, but overall confidence is fairly low. Continued northerly vertical wind shear and the storm's proximity to land will likely lead to some weakening during the next day or two, even if the center is able to remain just offshore. The bulk of the intensity guidance favors this scenario, and the updated NHC intensity forecast shows Cristina becoming a tropical depression by early Wednesday and dissipating on Thursday. This is in good agreement with the latest multi-model and simple intensity consensus aids. Alternatively, the circulation of Cristina could open up and dissipate earlier than forecast if it moves inland sooner than expected. The GFS deviates much farther to the south than the rest of the guidance, and the resulting intensification it shows is deemed an unlikely solution at this time. Key Messages: 1. Heavy rainfall associated with Tropical Storm Cristina will impact coastal portions of Central America through Thursday. This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain. 2. Tropical storm conditions, especially in gusts, are expected to impact portions of the coast of Nicaragua, El Salvador, and Honduras today.
