DISCUSSION AND OUTLOOK ---------------------- At 900 AM CST (1500 UTC), the center of Post-Tropical Cyclone Boris was located near latitude 16.9 North, longitude 98.9 West. The post-tropical cyclone is moving toward the northwest near 7 mph (11 km/h), and a west-northwestward motion is expected to continue today. Maximum sustained winds are now near 30 mph (45 km/h) with higher gusts. Boris is forecast to dissipate over the mountains of southern Mexico later today or tonight.

RAINFALL: The remnants of Boris are 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: Wind gusts to tropical-storm force will continue along portions of the coast of southern Mexico for a few more hours.

Issued at 900 AM CST Tue Jun 09 2026000 WTPZ42 KNHC 091446 TCDEP2 Post-Tropical Cyclone Boris Discussion Number 10 NWS National Hurricane Center Miami FL EP022026 900 AM CST Tue Jun 09 2026 Boris has continued to weaken as it moves farther inland. The low-level center has become very difficult to find even with the use of GOES 1-minute visible imagery, and the remaining convection is in a disorganized band along the coast of southern Mexico. Based on these developments, Boris has decayed to a remnant low pressure area and this will be the last advisory. The best estimate of the current motion is 305/6 kt. The remnants of Boris are expected to moved west-northwestward until the system dissipates completely in 12 h or so. Although Boris is decaying, there is a continued threat of heavy rainfall, which is the primary hazard of this slow-moving system. These rains will likely result in flash flooding and mudslides in mountainous terrain through today. Key Messages: 1. Heavy rainfall associated with the remnants of 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. Wind gusts to tropical-storm force may occur for the next few hours along portions of the coast of southern Mexico.

Tropical Storm Cristina Forecast Discussion Number 6
Issued at 900 AM CST Tue Jun 09 2026000 WTPZ43 KNHC 091446 TCDEP3 Tropical Storm Cristina Discussion Number 6 NWS National Hurricane Center Miami FL EP032026 900 AM CST Tue Jun 09 2026 Cristina continues to be affected by strong north-northeasterly vertical wind shear, and the cloud pattern is disorganized with little or no evidence of convective banding features. The center of the cyclone is estimated to be near the northern edge of the main area of convection. Given the current structure of the system, the current intensity is held at 35 kt for this advisory. This is in general agreement with objective estimates from UW-CIMSS. The center appears to be moving erratically near the northwest coast of Nicaragua, and the initial motion estimate is nearly stationary. The future track is uncertain and depends on whether the circulation remains intact while it meanders near the coast of Central America. If the center remains offshore, a slow west-northwestward motion is likely beginning within the next day or so, to the south of a mid-level ridge. The official track forecast is roughly in the middle of the numerical guidance. There is significant spread in the guidance models, so there is low confidence in this track forecast. Since Cristina is likely to remain near the coast of Central America, and northeasterly shear should continue over the area, a weakening trend is forecast to begin in a day or so. The tropical cyclone is forecast to dissipate over land in a couple of days. However if Cristina were to move inland sooner than expected, it will meet its demise earlier than indicated here. The official intensity forecast is in good agreement with the corrected consensus model guidance. 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.
