 Hurricane Felicia was the third strongest tropical cyclone of the 2009 Pacific hurricane season , as well as the strongest storm to exist in the eastern Pacific at the time since Hurricane Daniel in 2006 . Forming as a tropical depression on August 3 , the storm supported strong thunderstorm activity and quickly organized . It became a tropical storm over the following day , and subsequently underwent rapid deepening to attain hurricane status . Later that afternoon , Felicia featured a well @-@ defined eye as its winds sharply rose to major hurricane @-@ force on the Saffir – Simpson scale . Further strengthening ensued , and Felicia peaked in intensity as a Category 4 hurricane with sustained winds of 145 mph ( 230 km / h ) and a barometric pressure of 935 mbar ( hPa ; 27 @.@ 61 inHg ) . After reaching this strength , unfavorable conditions , such as wind shear , began to impact the storm while it took on a northwestward path . Henceforth , Felicia slowly weakened for several days ; by August 8 it had been downgraded to a Category 1 hurricane , once again becoming a tropical storm the next day . It retraced westward towards Hawaii on August 10 , all the while decreasing in organization . On August 11 , Felicia weakened to tropical depression status , and soon degenerated into remnant low just prior to passing over the islands .
