The Hurricane Research Division of NOAA conducted dual-aircraft experiments on successive days in Eastern-Pacific Hurricane Olivia (Sept. 24-25, 1994). On the 24th, the hurricane was embedded in weak easterly shear and moving to the west-northwest at 4 m/s. Observations from the lower-fuselage (LF) radar showed that the convection in Olivia's eyewall was highly asymmetric with the highest reflectivities located on the southeast side. During the time of flight, Olivia was intensifying, had flight-level winds of approximately 65 m/s, and a minimum sea-level pressure of 940 mb.
