Head of Data Information and Public Relations of the National Agency for Disaster Management (BNPB), Sutopo Purwo Nugroho, said that Jakarta still have to be vigilant. "Monitoring of weather satellites, this time the rain was still going on in Ciputat, Serpong, Parung, Cikupa, Ciawi, Cisarua. Fact on Mount Salak, heavy rains," said Sutopo when contacted VIVAnews.

While Katulampa floodgates this morning alert III status. While Manggarai Alert II with a height of 925 centimeters of water. Special Katulampa, he said, the water level is very volatile. Tuesday morning, January 15, 2013, Katulampa Standby status I had with a height of 210 cm. Then, the water quickly down to a height of 130 cm. "Hurry up, hurry down anyway," he explained.
This, according to him, shows that the flow of the river upstream has been damaged. So the rain just a little, could raise the water level quickly.
This condition is exacerbated by the conditions he Ciliwung river flow is a critical value. "Damaged. Settlements appear along Ciliwung flow."
To measure the flow of water, he added, there is the so-called coefficient of river regime. Ideally, the river had a coefficient is about 80-s. "Ciliwung was 180. Far from ideal," he explained. Poor condition is then impact downstream with flooding more severe.
