Keep those umbrellas close by — a heavy rainfall advisory has been issued in anticipation of some major storms that could be heading our way.

As much as 100 mm of rain could fall in Saskatchewan and Manitoba over the next four days.

The Shellmouth Dam is currently at the summer target level and the Qu'Appelle River is slightly higher than normal right now.

However, because it's been so dry, officials believe they'll be able to absorb more water than they did last year, when a major rainfall caused serious flooding.

Flash flooding or overland flooding is still possible, and communities in southwestern Manitoba are advised to take precautions.
