Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM EDT Sat Dec 1 2018
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
No tropical cyclones occurred in the basin during November, which is
not uncommon since a November tropical storm occurs about once every
other year.
Overall, the 2018 Atlantic hurricane season featured above normal
activity. Fifteen named storms formed, of which eight became
hurricanes and two became major hurricanes - category 3 or higher on
the Saffir-Simpson Hurricane Wind Scale. This compares to the
long-term average of 12 named storms, 6 hurricanes, and 3 major
hurricanes. There was also one tropical depression that did not
reach tropical-storm strength. In terms of Accumulated Cyclone
Energy (ACE), which measures the combined strength and duration of
tropical storms and hurricanes, activity in the Atlantic basin in
2018 was also above normal. In addition, 7 systems were
subtropical at some point in their lifetime this season, which
eclipses the previous record of 5 in 1969.
Reports on individual cyclones, when completed, are available at
