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

Three named storms and one tropical depression formed in the
eastern North Pacific basin in September. Two of the storms became
hurricanes in the basin, and one of these, Linda, became a major
hurricane. Based on a 30-year (1981-2010) climatology, three or four
named storms typically form in the basin in September, with two
becoming hurricanes and one reaching major hurricane strength.

In terms of Accumulated Cyclone Energy (ACE), which measures the
combined strength and duration of tropical storms and hurricanes,
activity in the basin so far in 2015 has been above normal. The ACE
through the end of September is about 25 percent higher than the
1981-2010 median value to date.

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