Temperatures are expected to be in the 20s all across the Okanagan by midweek, which means rapid snowmelt at higher elevations.

The above average snow packs indicate that spring runoff could be vigorous and may last well into June.

Flooding can occur when winter snow packs melt rapidly, overwhelming streams and creeks.

Spring freshet can also destabilize soil and rock, causing mudslides, landslides and rock slides.

Several low lying areas in the region went into the fall and winter with high levels of ground water saturation which has affected overland ground water movement this spring and may have contributed to some of the localized slides and debris flows, according to a statement from the Regional District of the South Okanagan.

The upcoming week of sunshine is a chance for residents across the Okanagan to prepare for possible flooding.

It's a good idea to sandbag properties that are near creeks, streams or waterways.

The RDOS has re-established sand and sandbag locations for residents.

Below are definitions the public should know in the case of an evacuation:

• Evacuation Order: You are at risk. Leave the area immediately. Local police or RCMP enforce evacuation orders.
• Evacuation Alert: Be ready to leave on short notice. If you leave before or during this alert, it’s called a voluntary evacuation.
• Evacuation Rescind: All is currently safe and you can return home. Stay tuned for other possible evacuation alerts or orders.
• Flood Warning: River levels have exceeded capacity or will exceed it imminently, and that flooding of areas adjacent to affected rivers will result.
• Flood Watch: River levels are rising and will approach or may exceed capacity. Flooding of areas adjacent to affected rivers may occur.
• High Streamflow Advisory: River levels are rising or expected to rise rapidly, but no major flooding is expected. Minor flooding in low-lying areas is possible.

The Emergency Operations Centre remains open and their number is 250-490-4225.
