As Hurricane Cristobal continued it northward motion east of Cape Canaveral, FL a NOAA P-3 collected airborne Doppler radar data to use in initializing and evaluating model guidance. Included here you see images of the horizontal winds within 300 km of Cristobal sampled from the tail Doppler radar on the P-3 aircraft during the evening of 26 August 2014. These images are at three altitudes (1 km, 3 km, and 6 km) and are a composite of winds from the P-3 Doppler pattern around Cristobal. Also plotted on each analysis are the locations of dropsondes deployed by the P-3 (plotted using standard station symbols). These analyses show that Cristobal started developing a more symmetric distribution of precipitation at all altitudes, but the bulk of the precipitation beyond 100 km from the center extended primarily in the eastern semi-circle of the storm. There is indication of a circulation center at all altitudes, with stronger winds 35-40 km east of the circulation center at 1-km altitude, and with a suggestion of a secondary wind maximum at 1- and 3-km altitude at 150-175 km to the east of the center. From 1-6 km altitude the circulation center exhibits very little tilt indicative of continued weakening of the horizontal wind shear since the last mission.

A NASA Hurricane and Severe Storm Sentinel (HS3) Global Hawk mission was conducted into Cristobal at the same time as this NOAA P-3 mission, dropping 81 dropsondes in a lawn mower type pattern over Hurricane Cristobal.
