Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM EDT Thu Nov 1 2018

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

October was above average in the Atlantic basin.  Three named
storms formed during the month, with a fourth (Leslie) beginning
in September and carrying over into October.  Three of these storms
became hurricanes during the month, and one became a major
hurricane.  This compares to October averages of two named storms
and one hurricane every year, and a major hurricane about every
third year.

In terms of Accumulated Cyclone Energy (ACE), which measures the
combined strength and duration of tropical storms and hurricanes,
activity in the Atlantic basin thus far in 2018 has been above
normal.  The season has already had 7 systems that were subtropical
at some point in their lifetime, which eclipses the previous record
of 5 in 1969.

Reports on individual cyclones, when completed, are available at
the National Hurricane Center website at
