Floods
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.
They say the measures of the past proved futile this time after the water level rose more than 1m higher than the massive floods in 1971.
"When it started to rain on Dec 3, we went to sleep at my sister's house nearby because it had never flooded there," said 59-year-old Kamariah Othman.
"But at 4am the next day, we were woken by her neighbour when water started flowing into their house.
"Before we knew it, we were up to our waists in water."
The family moved to a cousin's house on a hill and have been staying there for the past few days.

A Saudi labourer tries to clear a flooded street in northern Riyadh, on November 17, 2013, after heavy rains fell overnight in the Saudi capital, causing floods and traffic jams.
At least three people were reported missing, the state news agency SPA said quoting civil defence spokesman Colonel Abdullah al-Harithi.
He added that authorities assisted dozens of people trapped by the floods, a rare phenomenon to hit the capital of the desert kingdom.
Heavy rains, accompanied by thunderstorms, have lashed Riyadh since late Saturday triggering flash floods in several districts and cutting off power in the city's north, according to residents.

Note: this essay was written by the National Weather Service Forecast Office in Burlington, Vermont and tipped to me by a reader. Vermont's wind farm acreage pales in comparison to places like the Texas and Oklahoma, where there are literally thousands of acres of wind farms right in the middle of tornado alley. I've been there and seen them firsthand.
Certified Consulting Meteorologist Mike Smith writes:One has to wonder just how much trouble wind farms are causing the nation's doppler radar warning system. It looks like a classic case of the law of unintended consequences at work. - Anthony
"While driving to Norman, OK recently I saw the newest "wind farm" to the west of Interstate 35 southwest of Tonkawa. Wind farms show up as bright ground clutter on weather radars and here it is."
National Weather Service WSR-88D Radar and Wind Farm Impacts
Introduction
The most valuable tool used by the National Weather Service (NWS) to detect precipitation is the radar. Radar stands for Radio, Detection, and Ranging, and has been used to detect precipitation since the 1940′s, with most of the technology coming from the military.
Some of these changes are reflected in changes we can see occurring on other planets in our solar system, and may be related to the bizarre behavior of our sun and/or the nature of space around our solar system. Respected meteorologists and atmospheric scientists are warning of an impending ice age - the beginning of which could occur rapidly and with little warning. Secondary concerns have been widely expressed regarding worldwide food supply, not to mention rising prices and environmental instability.
The point here is not to stimulate panic. The point is to focus on what we can do as individuals and groups to prepare a living environment that is mindful of potential threats - an environment we can create with the means at our disposal. Just thinking and planning around this is preparation itself.

The typhoon has devastated up to 80 percent of the Leyte province area as it ripped through the Philippines, Chief Superintendent Elmer Soria told Reuters.
"We had a meeting last night with the governor and other officials. The governor said based on their estimate, 10,000 died," Soria said.
The Red Cross said earlier that 1,200 people we confirmed dead in the Philippines.

Filipino residents sleep on the floor at a gymnasium turned into an evacuation center in Sorsogon City, Bicol region, Philippines, on Nov. 7.
Super Typhoon Haiyan made landfall early Friday morning in Guiuan, a small city in Samar province in the eastern Philippines.
It reached the fragile island chain as the most powerful typhoon or hurricane in recorded history, says meteorologist Jeff Masters of Weather Underground
Thousands of people evacuated villages in the central Philippines on Thursday Haiyan took aim the region, which was devastated by an earthquake last month.
Haiyan had intensified and accelerated as it moved closer to the country with sustained winds of 195 mph and gusts of 235 mph, according to the U.S. Navy's Joint Typhoon Warning Center.
No Atlantic or eastern Pacific hurricane has ever been stronger than Haiyan (typhoons are the same type of storms as hurricanes).
About 10 million people live on the central Philippine islands and are most at risk from a direct strike from Haiyan.









Comment: So though it is described as a rare event, flooding according to the article also happened in May this year and in 2009 and 2011. Perhaps the rarity of flooding is a thing of the past for Saudi Arabia and many other places. In quick google search reveals just how common this is:
2009: Saudi Arabia floods leave 77 dead
2011: Saudi Arabia to Punish Officials for Damage After Jeddah Floods
April 2012: 18 Killed in Saudi Arabia Floods over Past Week
May 2013: Flash floods in Saudi Arabia leave 13 dead
August 2013: Eight people killed in Saudi Arabia flash floods
Increased precipitation is happening the world over and when the temperatures start going south then the precipitation will fall as snow and the onset of a mini/normal ice age is on the cards.
