hurricane felicia

This forecast uncertainty is conveyed by the track forecast "cone", the solid white and stippled white areas in the graphic. The solid white area depicts the track forecast uncertainty for days 1-3 of the forecast, while the stippled area depicts the uncertainty on days 4-5. Historical data indicate that the entire 5-day path of the center of the tropical cyclone will remain within the cone about 60-70% of the time. To form the cone, a set of imaginary circles are placed along the forecast track at the 12, 24, 36, 48, 72, 96, and 120 h positions, where the size of each circle is set so that it encloses 67% of the previous five years official forecast errors. The cone is then formed by smoothly connecting the area swept out by the set of circles.The National Hurricane Center says Hurricane Felicia's maximum sustained winds Wednesday have increased to near 105 mph. Felicia is expected to become a major hurricane later Wednesday.Meanwhile, Tropical Storm Enrique has maximum sustained winds near 50 mph and is expected to weaken and be absorbed by Felicia. Enrique is centered about 825 miles west-southwest of Baja California and is moving west-northwest near 15 mph.Felicia is centered about 1,365 miles west-southwest of the southern tip of Mexico's Baja California peninsula and is moving west-northwest near 12 mph.
