Air Force Reserve Hurricane Hunter aircraft measured flight-level winds of 154 knots and confirmed a central pressure of 917 mb inside Melissa’s eye — signs of an extremely powerful storm. The hurricane’s eye is just 10 nautical miles wide and surrounded by cloud tops colder than –86 °C, evidence of deep convection and explosive intensification. Melissa is expected to gradually turn northwest and then north before accelerating northeastward across southeastern Cuba and the Bahamas by midweek. Th

Ce bulletin fournit des détails techniques sur la structure et la trajectoire de l'ouragan Melissa, ainsi qu'une information cruciale concernant la sécurité : Structure et Intensité (Catégorie 5) : * Gradient de température impressionnant : L'œil de l'ouragan est analysé à -5°C, tandis que les sommets convectifs du mur de l'œil sont extrêmement froids, atteignant -85°C}. Ce gradient thermique très marqué témoigne de l'intensité et de la puissance extrême du cyclone (plus l'écart est grand, plus
