000 ABPZ20 KNHC 090716 TWOEP Special Tropical Weather Outlook NWS National Hurricane Center Miami FL 1215 AM PDT Wed May 9 2018 For the eastern North Pacific...east of 140 degrees west longitude: Satellite images indicate that showers and thunderstorms have become a little better organized this morning in association with a broad area of low pressure located more than 1100 miles southwest of the southern tip of the Baja California peninsula. Although recent satellite-derived surface wind data indicate winds of 30 to 35 mph were occurring on the northwest side of the disturbance, the low-level circulation remains elongated. However, only a slight increase in the amount and organization of the thunderstorm activity or an improvement in the surface wind field would result in the formation of a tropical depression later today while the system moves northwestward at around 10 mph. By late Thursday, upper-level winds are expected to become unfavorable for tropical cyclone formation. A Special Tropical Weather Outlook on this system will be issued by 11 AM PDT later today, if necessary. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...70 percent. $$ Forecaster Stewart
