How long do tropical storms last?
These life cycles may run their course in as little as a day or last as long as a month.

Why do tropical storms spin?
They are tropical revolving storms because they are spun on their journey by the Coriolis force of the Earth’s spin. The Earth is 40,000 kilometers (24,900 miles) around at its widest part, the equator. … It is this deflection that causes tropical storms to rotate.
How many miles across was Hurricane Sandy when it traveled by Florida?
Sandy’s minimum central pressure had risen to 952 millibars. The hurricane-force-winds extended 90 miles (150 km) east of the center of circulation. Tropical-storm-force winds, however, went much further, as far as 485 miles (780 km).
