For the eastern North Pacific, east of 140 degrees west longitude:

Six named storms formed during the month of August, but only one
of these became a hurricane in the eastern North Pacific basin.  The
one hurricane, Lester, also became a major hurricane.  Although the
total number of storms and major hurricanes in August is considered
near or above average, the number of hurricanes was below average.
Based on a 30-year (1981-2010) climatology, three named storms
typically form in the basin in August, with two of those becoming
hurricanes and one reaching major hurricane intensity.

In terms of Accumulated Cyclone Energy (ACE), which measures the
combined strength and duration of tropical storms and hurricanes,
August ACE was near average.  The ACE for the season to date
continues to be well above normal, about 175 percent of the
long-term average to date.

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