More than 5,000 people have been evacuated from flood-damaged homes in northern Gaza and at least one person killed in what the United Nations called "a disaster area".
The flooding, caused by four days of torrential rain, was so severe that many homes could only be accessed by rowing boat with water two meters deep in some places.
Severe weather in the form of heavy snowfall also paralyzed Palestinian cities such as Hebron and as well as Jerusalem.
Many people were trapped inside their houses and thousands of agency workers helped to evacuate stranded Palestinians to U.N. shelters.
Below are some photos and tweets that describe the horrible flooding disaster in gaza.
