Hurricane Sandy is the largest recorded Atlantic hurricane in diameter. It started as a tropical wave in the Caribbean on Oct. 22, and then became a tropical depression. This means that groups of thunderstorms have organized and that there is very low pressure, especially in the center of these storms. Six hours after it became a tropical depression, it was upgraded to a tropical storm, defined as a storm with winds from 39-73 mph. It has also become organized enough to start to look like the pictures of hurricanes we see on The Weather Channel. It was upgraded to a hurricane on Oct. 24, right before it hit Jamaica. It went back into the water and built up strength, upgrading to a Category 2 hurricane before striking Cuba on Oct. 25. A Category 2 hurricane, with winds from 96-110 mph, can cause a lot of damage, especially to objects and buildings that aren’t firmly rooted in the ground. It weakened to Category 1 (74-95 mph) and then became a tropical storm on Oct. 27, but quickly moved back to hurricane status. It hit the United States on Oct. 29 at around 8 p.m., slightly south of Atlantic City N.J. It was declared a post-tropical cyclone around 7 p.m., which means that the storm system became colder and connected with cold-weather fronts.
