Was Hurricane Beryl a special storm?
All hurricanes are special, given the extensive damage they can cause when they make landfall. Beryl was considered extra special because it was a record-breaking storm.
Beryl rapidly intensified from a tropical storm to a major hurricane (Category 3 or higher) with wind speeds that increased to 95 mph in less than two days. Category 3 storms have sustained winds between 111 mph and 129 mph. Only six other Atlantic Basin storms have intensified this quickly and those storms all happened after August, the typical time of year with conditions favorable for hurricanes. Continue reading
Why aren’t South America and the west coast of Africa hit by hurricanes?
Tropical storms hitting South America have distinct disadvantages compared with the North American situation. The energy to drive tropical systems is derived from warm ocean waters. For tropical storms to form, the ocean temperature needs to exceed 79.7 Fahrenheit, which … Continue reading

Are hurricanes intensifying more quickly?
Hurricane intensities are classified using the Saffir–Simpson scale, which rates hurricanes on a scale of 1 to 5 based on the damage their winds would cause upon landfall. Major hurricanes are those classified as Category 3 and higher on this … Continue reading

Do hurricanes affect Wisconsin?
A tropical cyclone is a rotating low-pressure system that has organized thunderstorms but no fronts. When a tropical cyclone’s maximum sustained winds reach 74 mph, it is called a hurricane. Hurricanes have never directly impacted the Upper Midwest region of the U.S.; however, the remnants of a hurricane or tropical storm have impacted the weather in the Midwest, including Wisconsin.
If a hurricane is particularly strong at landfall, it can move far enough northward to cause a significant rain event for areas in the Midwest. For the most part, such storms originally make landfall in Texas, Louisiana or Mississippi. These storms can be tracked by satellites or surface weather observations because they maintain an identifiable circulation pattern along their entire path. Continue reading
