The NOAA42 P3 aircraft is scheduled to fly today taking off from St. Croix around noon eastern. They will be flying an Ocean Survey mission. This mission will collect data to understand how the ocean and atmospheric play a role in the life cycle of a tropical cyclone. They will launch Airborne EXpendable BathyThermograph (AXBT) that measure ocean temperature as a function of depth and GPS dropwindsondes. Below is the proposed flight track. It may change depending on where the storm center is located. The dots on the flight track 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.
