Committee chairman Yasser Shanti said in a press conference that Israeli authorities had opened up dams just to the east of the border with the Gaza Strip earlier in the day.
He warned that residential areas within the Gaza Valley would be flooding within the coming hours.
He said that the move by Israeli authorities would flood areas in Moghraqa and other parts of Deir el-Balah in central Gaza, and he called upon residents of areas near the Gaza Valley to evacuate their homes in preparation for the anticipated flooding.
The Gaza Strip is currently under a state of emergency due to severe weather conditions caused by a historic storm front moving south across the Levant.
Fuel shortages have caused daily life in the Gaza Strip to grind slowly to a halt since early November, as power plants and water pumps are forced to shut down, cutting off access to basic necessities for Gaza residents.
Lack of diesel fuel is a result of the tightening of a seven-year-long blockade imposed on the territory by Israel with Egyptian support.
The Gaza Strip has been under a severe economic blockade imposed by the State of Israel since 2006
