Sri Lanka has been battered with heavy showers in the last 24 hours wherein isolated pockets also saw three digit rainfall activities.
A trough was extending from equatorial Indian Ocean up to Sri Lanka due to which northern, southern as well as eastern districts of the Sri Lankan nation saw extremely heavy rainfall activities. Rainfall intensity was less over the western districts.
In the last 24 hours from 8:30 am on Monday, Trincomalee saw a whopping 106 mm of rainfall, Colombo saw a whopping 71 mm of rains, Mannar 48 mm, Anuradhapura 41 mm, Vavuniya 42 mm, Batticaloa 31 mm, Pottuvil 24 mm and Galle 20 mm.
Now, light to moderate showers with one or two heavy spells are expected to continue over Sri Lanka for another 24 hours. Thereafter, the trough will move towards the south, which is, away from Sri Lanka, thus, rains will reduce to quite an extent.
However, scattered light rainfall activities are expected to continue over Sri Lanka for the next three days. In fact, rains will once again pick up pace around February 10.
Usually, Sri Lanka sees good rainfall activities both during the Northeast as well as the Southwest Monsoon season. After Northeast Monsoon, rainfall intensity over Southern Peninsular India decreases. Weather, therefore, becomes almost dry but due to on and off formation of weather systems over Equatorial Indian Ocean, Sri Lanka does receive good rains.
Moreover, the semi-permanent feature, which is a trough from Southeast Bay of Bengal to Equatorial Indian Ocean across Sri Lanka, ends up giving good rains over the country.
