The primary focus of today's discussion revolves around the significant impacts of Hurricane Melissa as it navigates between the central Bahamas and Bermuda, specifically highlighting the consequential marine hazards and instances of minor coastal flooding along the Mid Atlantic and Northeast coastlines. We elucidate the various advisories issued by the National Weather Service, which indicate a marginal risk of severe weather, inclusive of damaging winds and the potential for isolated tornadoes. Additionally, we examine the coastal flood advisories that have been enacted across multiple states, notably affecting areas from Delaware to New York City, where localized road closures are anticipated during high tide. Furthermore, we provide insights into the expected wind and rain events in Maine, alongside the heightened water levels observed along the Chesapeake Bay and Tidal Potomac shorelines. Our aim is to keep our audience informed and prepared as we navigate these weather phenomena.
