On August 11, Tropical Depression Eight developed southwest of Fort Myers, Florida. It quickly moved ashore, reaching Lake Okeechobee before looping to the northwest. While moving across the state, it dropped heavy rainfall of around 10 in (250 mm) along the west coast.[4][12] In Pinellas Park, the heavy rains led to flash flooding that forced 200 families from their house, including one that required evacuation from a helicopter.[13] Damage in the region was estimated at $250,000 (1971 USD, $1.51 million 2018 USD).[14]
