GOES-16 TPW Near Cindy

On 21 June, Tropical Storm Cindy approached the Louisiana Gulf Coast. The main threat with this system was heavy rain and flooding. The GOES-16 TPW baseline product provides forecasters with rapidly updating information about how much moisture is available in the atmosphere. Widespread TPW over 2.0" was sampled in the vicinity of Cindy, with some localized areas over 2.5" (Fig 1). These observations agree with nearby radiosonde data (LIX), which measured 2.36" of PW  (Fig 2).
