The timing of the rain will continue through today.

Showers and thunderstorms are expected again today. Extremely heavy rain fell yesterday, surpassing 100 mm over a few locations. Additional rainfall is expected to result in further impacts today. Locally higher amounts are possible in thunderstorms.

This weather pattern typically brings rapidly changing conditions between sunny skies and heavy downpours.

Showers and thunderstorms are expected to taper to isolated showers tonight.

Localized flooding in low-lying areas is possible.

Avoid driving through water on roads. Even shallow, fast-moving water across a road can sweep a vehicle or a person away. Don’t approach washouts near rivers, creeks and culverts.

Keep children and pets away from creeks and river banks. Consider moving valuable items to higher levels.
