கொழும்பில் பல வீதிகள் வெள்ளத்தில் மூழ்கின - கடும் வாகன நெரிசல்!

Daily Mirror reports that Colombo Municipal Council officials attributed flash flooding on the 6th to around 129 millimetres of rain falling in an hour. The Sunday Times reports that the downpours also brought heavy traffic, while Newsfirst (සිංහල) says roads in Colombo and nearby areas were inundated, disrupting daily life.

Newswire reports that Meteorology Department Director General Ajith Wijemanna linked the intense rainfall to the Intertropical Convergence Zone and prevailing second inter-monsoon conditions, which he said helped create conditions for strong afternoon thunderstorms. Newsfirst reports that the department measured more than 100 millimetres across Colombo in less than an hour the previous evening.

Newswire reports that rainfall intensity exceeded 120 millimetres an hour in Colombo and 135 millimetres an hour in Mattakkuliya. The outlet says blocked drains, including those obstructed by human activity, slowed runoff in Colombo Fort and other urban locations, worsening temporary flooding.

Newswire reports that floodwaters receded in several affected areas within about two to three hours. It also says Colombo recorded larger total rainfall in past extreme-weather events, including 493 millimetres in 1992 and 440 millimetres in 2010, while Wijemanna identified the short-period intensity rather than the total rainfall as the key factor in this flooding.

Newswire reports that Thimbirigasyaya received 146.6 millimetres in the 12-hour period ending at 6 a.m. on the 7th.
