Hurricane Melissa is forecast to become a Category 5 storm within 48 hours before impacting Jamaica, potentially causing catastrophic and life-threatening conditions, according to multiple sources. The National Hurricane Center (NHC) issued updated key messages on October 25th, emphasizing that damaging winds and heavy rainfall are expected to begin in Jamaica tonight. These conditions are predicted to cause catastrophic flash flooding, numerous landslides, extensive infrastructural damage, prolonged power and communication outages, and potential isolation of communities. A life-threatening storm surge is also likely along portions of the southern coast early next week. Residents have been advised to complete all preparations immediately. Meteorological sources, including NHC_Atlantic via X.com, reported at 5 PM EDT on October 25th that Melissa's impact on Jamaica will include severe damage and long-duration outages. WxNB_ also reported via X.com that all signs point to a potentially catastrophic event. Separately, storm chaser Jordan Hall, in a post on X.com approximately one hour before his scheduled flight to Montego Bay, Jamaica was cancelled, cited safety concerns and insufficient preparation as reasons for not pursuing Hurricane Melissa. Hall stated that while he often makes last-minute decisions during chases in the United States, he handles international chasing differently, prioritizing safety to ensure continued coverage of future storms. The NHC's key messages also extended warnings to other Caribbean nations. Haiti is expected to experience catastrophic and life-threatening flash flooding and landslides across its southwestern region into early next week, with strong winds potentially lasting over a day in the Tiburon peninsula. The Dominican Republic could see catastrophic flash flooding and numerous landslides in its southern areas due to heavy rainfall. Eastern Cuba, the Southeast Bahamas, and the Turks and Caicos are advised to monitor Melissa closely, as the risk of significant storm surge, damaging winds, and heavy rainfall is increasing by the middle of next week. A Hurricane Watch is currently in effect for portions of eastern Cuba. The National Hurricane Center had previously issued a warning to Jamaica on Saturday, October 24th, stating that the storm surge could potentially reach 9 to 13 feet above ground level in affected areas. The storm's slow and erratic path since advisories began on October 21st was also noted.
