Tropical Storm Melissa Forecast to Become Major Hurricane, Threatening Caribbean

Tropical Storm Melissa Intensification

• 🌀 Tropical Storm Melissa is currently in the central Caribbean and is expected to strengthen rapidly into a major hurricane over the weekend.
• 🌡️ The storm is forming over 90°F sea surface temperatures in the central Caribbean, providing ample energy for intensification.
• 📈 Above-normal ocean heat content in the central and western Caribbean further fuels the storm's potential.
• 🌬️ Light upper-level winds are forecast, allowing the storm to remain vertically stacked and tap into the available energy.

Potential Impact on the Caribbean

• ⚠️ Jamaica and Hispaniola are at significant risk of dangerous conditions, including hurricane-force winds and life-threatening flash flooding.
• ⛰️ Mountainous terrain in Hispaniola is expected to squeeze out heavy rainfall, exacerbating flood risks.
• 🌊 Rainfall totals could reach 30 inches in Jamaica and 20-30 inches in Haiti and the Dominican Republic, with potential for mudslides.
• 🇨🇺 Eastern Cuba may also experience significant rainfall, potentially up to 15 inches.

Storm Track and Future Outlook

• 📍 Forecast models show Melissa moving very slowly, potentially remaining stationary for several days, intensifying into a Category 4 hurricane.
• 💨 A cold front approaching from the north is expected to eventually sweep the storm out to sea, preventing it from threatening the U.S. Gulf Coast.
• 🌊 The storm's trajectory may shift it towards the East Coast, potentially bringing rain to the Northeast.

U.S. Weather Impact

• 💨 A cold front will bring breezy and cool conditions to Houston for Halloween.
• 🌧️ A separate rain event is expected in Houston on Saturday, with potential for several inches of rain.
• 🌬️ A subsequent midweek front will bring gusty northwest winds of 20-25 mph.
