Updated on April 15. 1:20 PM (IST): Heavy rains continue to lash many parts of Sri Lanka even during the last 24 hours. In fact, a few spells of rains were also recorded over the nation.

During the last 24 hours from 8:30 am on Saturday, Puttalam saw 45 mm of rains, Nuwara Eliya 40.5 mm, Maha Illuppallama 16 mm, Kurunegala 9 mm, and Colombo 4.8 mm.

These rains occurred due to a cyclonic circulation over Comorin region along with which a trough is extending from this system.

These rainfall activities are expected to continue for another 24 hours and thereafter, there will be a reduction in these weather activities.

Updated on April 14 at 3:10 pm: As predicted by Skymet Weather, various places in Sri Lanka recorded light to moderate rains with few heavy spells. In the last 24 hours from 8:30 am on Friday, Vavuniya recorded heavy rain to the tune of 55.1 mm, Puttalam 51.7 mm, Nuwara Eliya 31.5 mm, Kurunegala 26.7 mm and Colombo 18.4 mm rains.

The cyclonic circulation which was lying over Sri Lanka and adjoining Indian Ocean has weakened and is moving away westwards. Hence, the rainfall activity will be decreasing gradually over Sri Lanka.

However, during the next 24 hours, light to moderate rain at scattered places will continue. Thereafter, rain intensity will decrease significantly over the country. In fact, the day temperatures will also rise during that time. Meanwhile, minimum temperatures are expected to reduce marginally.

Updated on April 13 at 4:10 pm: Sri Lanka has been recording light to moderate rains with few heavy spells for the past three to four days. However, the intensity of rains increased during the last 24 to 48 hours.


In the last 24 hours from 8:30 am on Thursday, Ratmalana recorded heavy rain to the tune of 52.4 mm, followed by Galle at 49 mm, Katunayake 31.2 mm, Anuradhapuram 25.7 mm, and Vavuniya 14.6 mm rains. In the same time frame, Batticaloa witnessed 12.8 mm, Pottuvil 4.3 mm, Kandy 3.2 mm and Trincomalee 2.9 mm.

As per Skymet Weather, the prevailing cyclonic circulation over Sri Lanka and adjoining regions was responsible for the rains. However, this cyclonic circulation is expected to move in the west direction. Therefore, the intensity of rains is likely to reduce now.

However, light to moderate rain and thundershower activity will continue over many parts of the country. In fact, the southern regions are expected to record heavy to very heavy spells as well. These weather activities are expected to continue during the next 48 hours. Thereafter, there are chances of scattered rainfall activity.

Places like Galle, Ratmalana, Katunayake, and Anuradhapauram are anticipated to observe good pre Monsoon showers. Capital city Colombo might also witness light rainfall activity. The weather is humid over the country, due to its close proximity to the coast.
