FOR THE EASTERN NORTH PACIFIC, EAST OF 140 DEGREES WEST LONGITUDE:  
 
TWO TROPICAL STORMS FORMED IN THE EASTERN NORTH PACIFIC BASIN IN  
OCTOBER, BUT NEITHER ATTAINED HURRICANE STATUS. BASED ON A 30-YEAR  
(1981-2010) CLIMATOLOGY, TWO NAMED STORMS TYPICALLY FORM IN THE  
BASIN IN OCTOBER, WITH ONE OF THOSE BECOMING A HURRICANE. A MAJOR  
HURRICANE OCCURS IN THE BASIN IN OCTOBER IN ABOUT 6 OUT OF 10  
YEARS.  
 
IN TERMS OF ACCUMULATED CYCLONE ENERGY (ACE), WHICH MEASURES THE
