590 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.
