The NOAA43 aircraft is ready to fly into AL99 – the tropical disturbance north of Hispaniola. The aircraft will take off at 2:00AM eastern time for an eight hour mission to and from MacDill Air Force Base in Tampa, FL. The science objective of this flight is to collect data in the environment as well as the inner core of the disturbance. It will help us understand how storms develop (or not develop). This will be the first flight in a series of flights that will fly every 12 hours until the system makes landfall or dissipates. Below is the 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.
