Issued at 05.30 a.m. on 18 December 2025

Showery conditions are expected to persist across several parts of Sri Lanka today

Rainfall is forecast at times in the **North-Central, Eastern, Uva and Central provinces**,
with **fairly heavy showers exceeding 75 mm** likely in some areas of the Eastern
and Uva provinces, the Central Province and the **Polonnaruwa district**.

The **Northern and North-Western provinces** may experience several spells of showers
throughout the day, while **showers or thundershowers** are expected in many other
parts of the island after **1.00 p.m.** Fairly heavy rainfall above **50 mm** is
possible in isolated locations during these afternoon and evening showers.

Meanwhile, **strong winds ranging between 40 and 50 kmph** are anticipated at times
over the **eastern slopes of the central hills**, as well as in the **Northern, 
North-Central and North-Western provinces**. Similar windy conditions may also affect**
Trincomalee, Hambantota and Monaragala districts**.
