NOAA’s P3 hurricane hunter aircraft is set to fly into Tropical Storm Karl. They will take off at 2AM for an eight hour mission from St. Croix. The data collected on this and all the flights helps us understand the interaction between Karl and its surrounding environment. Below is the proposed flight track. The dots on the flight track (shown in green) represent the aircraft turn points. The red dots in the figure show the locations that launch weather balloons twice a day while the purple dots are the locations that launch balloons once a day.
