NHC: 卫星观测史以来东北太平洋最早生成的TC Overnight ASCAT data showed the disturbance over the central easternPacific basin has developed a well-defined center. Furthermore,convection associated with the low has increased in organizationsince yesterday. Advisories have therefore been initiated onTropical Depression One-E. The initial intensity is set at 30 ktbased primarily on the aforementioned ASCAT data. This marksthe earliest formation of a tropical cyclone in the eastern NorthPacific basin since the satellite era began in 1966. The depression is not expected to stick around for long. Dry air inthe surrounding environment appears to have already wrapped aroundmuch of the cyclone's circulation, and this is likely limiting itsassociated convection. This should also prevent the depression fromstrengthening much during the next 24 h, but it can not be ruled outthat the system could briefly become a tropical storm later today.On Sunday, an increase in vertical wind shear and lower SSTs alongthe forecast track will contribute to the depression's demise, andit is expected to become a remnant low within about 36 h, if notsooner.
