Showers or thundershowers are expected to occur at several places in the Western,
Sabaragamuwa, and Southern provinces, as well as in the Nuwara Eliya district after
1.00 p.m. today. These afternoon showers may bring temporary heavy rainfall in localized
areas, along with strong gusty winds and lightning. Residents in these regions are
advised to remain cautious, especially during evening hours when thunderstorm activity
is more likely to intensify.

In contrast, mainly dry weather will prevail across most other parts of the island,
providing relatively stable and warm conditions. However, misty conditions can be
expected during the early hours of the morning in the Central, Sabaragamuwa, and
Uva provinces, as well as in the Galle, Matara, and Kurunegala districts. Motorists
are advised to drive carefully due to reduced visibility during early morning hours.

The Department of Meteorology further indicates that atmospheric conditions are 
becoming increasingly favorable for evening thundershowers across most parts of 
Sri Lanka from 20 April onwards. This suggests a gradual increase in rainfall activity
in the coming days.
