|Watch A Former Hurricane Wind Down |
Rapid intensification of tropical storms and hurricanes often gets the most attention from meteorologists, for good reason. When that happens near land, it can be a nightmare for emergency managers and the public to react to and prepare for ahead of the storm.
Fortunately, we have a story of a weakening former hurricane today. Calvin topped out at Category 3 strength Friday, but weakened to a tropical storm Sunday, and is forecast to be either a tropical storm or tropical depression by the time it reaches Hawaii late tomorrow night or early Wednesday, local time.
You can see the weakening in the satellite loop above. First the eye became less distinct, then the spiral bands of rain became less organized and smaller.
Cooler water, and drier, more stable air weakened Calvin. It’s a scenario that often happens with hurricanes that approach Hawaii from the east. Hawaii’s rare hurricane strikes usually happen from storms that first form closer to the islands, then curl north.
So, Calvin was an example of a hurricane to love, if you’re a weather geek. It became strong in the middle of the ocean, was beautiful to look at in satellite imagery, but has weakened considerably as it is drawing closer to land. If only the rest of the hurricanes this season would do that or simply curl harmlessly out to sea.
