There is a risk of thundershowers for parts of western Newfoundland today and tonight, while the White Bay and Green Bay region is being warned to prepare for heavy rainfalls today and Saturday.
Environment Canada has issued a rainfall warning for much of central and eastern Newfoundland, stretching as far west as the White Bay area.
The alert states that showers will develop in the areas under the warning today and become heavy at times tonight. Rainfall amounts of 20 to 30 millimetres are expected, with local amounts up to 60 millimetres possible by Saturday morning. Additional amounts up to 15 millimetres are also expected Saturday in the northeast and central regions.
Heavy downpours can cause flash floods and water pooling on roads. People are being urged to watch for possible washouts near rivers, creeks and culverts.
Meanwhile, there is a chance of thundershowers in western Newfoundland from Port aux Basques to Deer Lake and vicinities today and into the evening. Rainfall amounts are expected to be around five millimetres, but could get as high as 15 millimetres in places.
Showers will continue Saturday, tapering off for Sunday.
The Northern Peninsula will also see showers throughout today and Saturday before they clear up Sunday.
Temperatures throughout western Newfoundland should reach between 20 and 22 C today, but dip to between 16 and 19 C for Saturday and 18 to 20 C Sunday.
