...FLASH FLOOD WARNING FOR SOUTHWESTERN BROOME AND EASTERN TIOGA 
COUNTIES HAS BEEN REPLACED WITH A FLOOD WARNING...

The heaviest rain has ended with light to moderate rain expected 
overnight. Roads were still flooded in a few areas so the flash 
flood warning which is for rapid flooding has been replaced with a 
flood warning. Water is still covering roadways in some areas of 
southwest Broome County and Eastern Tioga County. The water was 
receding but some flooding will linger on roadways. Expect the water 
to further recede by 3 am.
