Storm type
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionAt 18:00 UTC on November 26, the India Meteorological Department (IMD) began to track a depression formed from a well marked low just offshore the southeastern coast of Sri Lanka, due to favourable conditions such as high sea surface temperatures and mid-level vertical wind shear being low (10–15 knots).[1] The depression would intensify further, first into a deep depression at 00:00 UTC on November 27, then into a Cyclonic Storm at 06:00 UTC, when it received the name Ditwah,[2] which is the name provided by Yemen, referring to the Detwah Lagoon on Socotra Island. Ditwah’s clouds have become increasingly organised into a curved band pattern.[2]

Impact

Perspective
Heavy rains caused flooding and landslides in Sri Lanka, resulting in more than 123 deaths, 40 injuries and 130 missing persons.[3][4][5][6] More than 25 deaths occurred in the cities of Nuwara Eliya and Badulla, while 20 others were reported missing after a landslide struck the village of Gangoda in Kandy District.[7] Three people were killed in Ampara after their car was swept away by floodwaters. Reservoirs and rivers overflowed, blocking roads, and key roads connecting affected provinces were closed. Authorities stopped trains in some areas in the mountainous region after mud, rocks and trees fell onto railway tracks, with some of them being inundated by floodwaters.[8] Severe weather caused widespread power outages, affecting 25 to 30 per cent of the region. Two major hydropower plants, Kotmale and Rantambe, were shut down after a power cable failure. Scores of houses were destroyed, leaving thousands homeless. According to latest sources, as many as 373,428 people from 102,877 families were affected by the widespread flooding, while 43,925 families took shelter in 488 emergency centres.[5]Nearly 300 people were left stranded at Colombo's Bandaranaike International Airport for three days after multiple flights were cancelled.[9]In India, authorities cancelled 54 flights at Chennai International Airport and shut schools in Tamil Nadu, ahead of the approach.[10] A red alert was issued for some parts of Tamil Nadu.[11]
