Thereafter, it maintained intensity as it struck the Lesser Antilles later that day. Over the next three days, Donna deepened significantly and reached maximum sustained winds of 130 mph (210 km/h) on September 4. Of course, that slow movement near land led to massive, widespread flooding in Louisiana, Mississippi, Alabama and Florida. Donna moved west-northwestward at roughly 20 mph (32 km/h) and by September 1, it reached hurricane status. Hurricane Juan in 1985 did even better, looping twice near the Louisiana coast. This page has some cool hurricane records. In this way, you can get a loop, as occurred with Jeanne in 2004 before its eventual Florida landfall. This bitch about to make landfall just south of Ft Pierce, FL and she instead chills right off the coast for over 24 hours wreaking havoc and then comes ashore and very slowly. Once that same high-pressure system aloft moves to the east, the hurricane or tropical storm will curl back toward the west, then northwest again. Often in a looper case, a weak disturbance in the jet stream will brush to the north of the hurricane or tropical storm, pulling it northeast or east, but won't be strong enough to carry it away.īehind that, higher pressure aloft will then curve the system back toward the south. A few performed multiple loops, with paths resembling a helix. These tropical storms and hurricanes made at least one loop, crossing their previous path once or more. We have many examples of each in our slideshow atop this article. These tended to fall into several categories. The paths these storms trace out may resemble a child's first drawing, proudly displayed on the refrigerator. Some hurricanes and tropical storms, however, take stranger journeys. Those forecast tracks are relatively straightforward. In these cases, the atmosphere's steering flow is strong and persistent enough to keep the hurricane on a steady path. Some tropical cyclones follow very clear tracks – for example, a curve around the south and west sides of the Bermuda-Azores high in the Atlantic Basin, or just a straight buzzsaw through the Caribbean Sea. The twisty, curvy forecast path of Eta over the next several days is a reminder that hurricane paths often aren't relatively straight lines. Leslie meandered over the North Atlantic Ocean for more than two weeks before finally approaching the Iberian Peninsula, where it held on to hurricane strength until it was within 195 miles of.
