Satellite Images Reveal Mesovortices in Hurricane Melissa’s Eye

Hurricane Melissa, a Category 5 storm, has caused significant destruction across the Caribbean, and its intensity has been captured by satellite imagery. On October 28, 2023, the GOES-19 satellite revealed the formation of “mesovortices” around the hurricane’s eye, according to the National Oceanic and Atmospheric Administration (NOAA). These small-scale rotational features emerge under conditions of extreme differences in wind speed and direction, contributing to the storm’s power.

The hurricane struck Jamaica with winds reaching up to 185 miles per hour (approximately 295 kilometers per hour), marking it as one of the most formidable hurricanes recorded in the Atlantic Ocean. As the storm ravaged the island, emergency authorities reported at least four fatalities in southwest Jamaica. Desmond McKenzie, deputy chair of Jamaica’s disaster risk management council, refrained from detailing the death toll but confirmed the widespread impact on infrastructure. Currently, around 72% of the island is without power, and 65% of mobile phone sites are down.

As Hurricane Melissa continued its path, it affected neighboring regions as well. In Haiti, at least 25 people lost their lives, with an additional 18 individuals reported missing due to severe flooding. While Cuba experienced the storm as a Category 3 hurricane on October 29, 2023, there have been no confirmed fatalities. However, many communities are still facing significant disruptions, lacking electricity, internet, and phone services due to damaged infrastructure.

Current Status of Hurricane Melissa

As of the morning of October 30, 2023, Hurricane Melissa has been downgraded to a Category 2 storm with sustained winds nearing 105 miles per hour (about 169 kilometers per hour). The hurricane is located approximately 515 miles (around 830 kilometers) southwest of Bermuda, which is currently under a hurricane warning.

The destruction wrought by Hurricane Melissa highlights the increasing intensity and frequency of extreme weather events, a trend that is exacerbated by climate change. As nations grapple with the immediate and long-term effects of such storms, the need for robust disaster management and climate resilience strategies becomes ever more pressing. The ongoing assessments and recovery efforts will be critical in addressing the damage and ensuring the safety of those affected by this powerful storm.
