Eyewitnesses said many residential areas and farming land east of Gaza city were flooded when the Israeli authorities opened up the dams.
The residents of the area appealed to the concerned authorities to intervene before sewage water completely submerge their properties.
Earlier on Friday, Chairman of Government's Disaster Response Committee Yasser Shanti said the Israeli authorities opened up dams just to the east of the border with the Gaza Strip earlier in the day.
He warned that the residential areas within the Gaza Valley would be flooding within hours, saying the move would flood areas in Moghraqa and other parts of Deir el-Balah in central Gaza.
Shanti 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 Israeli occupation since 2006.
People with conscience should be appalled at the situation in Palestine.
It should be the beginning of every conversation, but the silence is deafening.
