On April 25, 1979 it rained. And rained. And rained.
The National Weather Service recorded nearly 18 inches of rain in Boca Raton as an area of low pressure over the eastern Gulf of Mexico interacted with a large high poressure system over the western Atlantic.
Fort Lauderdale saw 14.6 inches of rain. West Palm Beach recorded about 6.5 inches.
According to the April 26 edition of The Palm Beach Post, schools of fish swam in the streets of Delray Beach, cars were left abandoned and people had to be evacuated and schools were shuttered.
“We had two feet of water in the gymnasium and in the shops,” said Arthur Palin, then principal of Forest Hill High School in West Palm Beach. “The roofs of 16 classrooms and two offices were all wet and some were falling down in flooded hallways.”
The NWS in Miami says that before this rainfall, most of South Florida had been in a moderate drought during April, that resulted in water restrictions.
