Municipal crews are working around the clock with limited tools and resources to mitigate the impact of the storm, Mhana added.
He warned of deteriorating health and environmental conditions if the storm continues, particularly due to the mixing of rainwater with sewage in some areas.
About 1.9 million people in Gaza, out of a population of 2.4 million, remain displaced and live in harsh conditions in worn-out tents after their homes were destroyed during the war.
Israel escalates attacks in the occupied West Bank
The Israeli attacks continue beyond Gaza, as Israeli forces carried out raids in northern West Bank towns, wounding eight Palestinians, including members of an ambulance crew, Palestinian officials said.
The Palestinian Red Crescent said its teams in Tulkarem treated seven people injured in beatings during an attack by illegal Israeli settlers in the town of Ramin. Two of those injured were taken to a hospital for medical attention.
In the town of Huwara, south of Nablus, a 49-year-old Palestinian was shot in the foot during another attack, the organisation said.
Illegal Israeli settlers have escalated attacks against Palestinian towns and property across the occupied West Bank since the Gaza war in October 2023. Murders, arson, theft, and other crimes by the occupants, including incidents caught on camera, have gone almost entirely unpunished.
According to Palestinian figures, at least 1,133 Palestinians have been killed and about 11,700 others injured in attacks by the Israeli army and illegal settlers in the occupied territory since October 8 2023.
Approximately 750,000 illegal Israeli settlers reside in hundreds of illegal settlements in the occupied West Bank, including 250,000 in East Jerusalem, and they perpetrate daily attacks against Palestinian civilians to forcibly displace them.
In a landmark opinion in July 2024, the International Court of Justice declared Israel’s occupation of Palestinian territory illegal and called for the evacuation of all settlements in the occupied West Bank and East Jerusalem.
