Tropical Storm Melissa Could Become Category 5 Hurricane: AccuWeather Forecaster Alex DaSilva

Tropical Storm Melissa's Current Status and Forecast

• 🌪️ Tropical Storm Melissa is currently located south of Haiti and is disorganized due to significant wind shear from the northwest.
• 📈 However, the wind shear is expected to decrease, allowing Melissa to strengthen, with rapid intensification predicted for the weekend.
• 🎯 Forecasts indicate Melissa could become a Category 3 major hurricane by Sunday and potentially a Category 4 or 5 by early next week.
• 🇯🇲 Landfall is projected in western Jamaica on Tuesday as a major hurricane.

Potential Impacts on Puerto Rico and the US Mainland

• 🌧️ Puerto Rico is already experiencing heavy rain from outer bands of the storm, with localized flash flooding expected to continue.
• 🚢 The favored track for Melissa is eastward, away from the United States mainland, heading towards Bermuda.
• ⚠️ Despite the favored track, some model guidance suggests a westward shift, potentially bringing impacts closer to the US coast, from Florida to Atlantic Canada.
• 🌊 Even if the storm stays offshore, dangerous rip currents and beach erosion are anticipated along the US East Coast starting mid-next week.

Catastrophic Flooding Risks in Haiti and Jamaica

• 🌊 The storm's disorganization is causing widespread rainbands, leading to significant flooding in Puerto Rico and the Dominican Republic.
• 🆘 Catastrophic flooding and a potential humanitarian crisis are projected for western Haiti and Jamaica due to the storm's slow movement and heavy rainfall, potentially measured in feet.
• ⛰️ Mountainous terrain in these regions will exacerbate flooding and mudslides, as deforestation limits the land's ability to absorb water.
• 🚢 A storm surge of 6 to 10 feet is possible in Jamaica, with localized surges potentially reaching 15 feet, particularly around Kingston.

Recommendations and Forecast Uncertainty

• ⚠️ Residents in affected areas are strongly advised to heed the advice of local officials, especially regarding evacuations from riverine flood zones and potential mudslide areas.
• 🗺️ The slow and meandering nature of the storm creates significant forecast uncertainty, making it crucial to follow daily updates from AccuWeather.
• 💨 While direct impacts on the US mainland are not currently expected, vigilance is advised as the forecast can change significantly over the coming days.
