Environment and Climate Change Canada (ECCC) reports the possibility of heavy precipitation in southern and central Manitoba. Precipitation will begin to intensify over southern Manitoba by the morning of Thursday October 10. There is a risk of heavy rain, snow, freezing rain, strong winds and freezing temperatures. Most areas of Manitoba are expected to transition to snow by early Saturday October 12. Heaviest precipitation will begin to tapper off by Monday October 14 with a chance of flurries and/or showers persisting until Thursday October 17. This precipitation will fall on already saturated soil. The map below displays total accumulations of precipitation/snow to Monday, October 14 at noon.
Levels on rivers, creeks and lakes in southern Manitoba continue rise. Manitoba Infrastructure’s Hydrologic Forecast Centre (HFC) has issued a high water advisory for southeastern Manitoba and Whiteshell Lakes. Due to expected high winds, HFC has issued high wind effect warnings for the south basin of Lake Manitoba, Lake Winnipeg, Dauphin Lake and for Winnipegosis.
Manitoba Hydro reports that heavy, wet snow combined with fall foliage could result in broken tree branches, potentially impacting electrical infrastructure. Quickly falling temperatures will cause rain to freeze on power lines, poles and transformers which can result in power outages and damage to Manitoba Hydro infrastructure. Poor travel conditions will result in increased response times and slow power restoration activities.
To lower Red River levels in the City of Winnipeg HFC reports the Red River Floodway may be activated as early as Wednesday evening. This floodway operation may cause artificial flooding for property owners upstream of the floodway control structure.
ECCC will continue to issue weather related watches and warnings as required.

Municipalities may want to consider the following preparedness activities:
· Review emergency plan, EOC activation process, and contact lists,
· Ensure municipal equipment for road and debris clearing is in good working order,
· Review how to report emergency information to EMO on our website https://www.gov.mb.ca/emo/response/report.html,
· Review the requirements and process for declaring a state of local emergency,
· Review emergency public alerting/public messaging procedure, and
· Consider impacts/consequences to continuity of critical services should there be prolonged electrical outages.
Preparedness messaging for residents for adverse weather include:
· Having an emergency kit. Information about what should be in a kit can be found at https://www.gov.mb.ca/emo/prepare/kit.html.
· Store warm clothes and blankets where they can be accessed easily.
· Ensuring that furnaces are working properly in case of a sudden drop in temperature.
· Ensuring sufficient fuel is on hand for generators in case of a prolonged power outage and practice proper safety procedures.
· Consider winter or all season tires for vehicles and drive to the conditions. Roads may be slippery as a result of snow, ice and wet foliage. Avoid driving if conditions are unfavourable.
· Be aware of surroundings. Watch for downed trees or damaged power lines that have fallen as the result of high winds or accumulated ice.
· Keep fridge and freezer doors closed in the event of a power outage.
· Check on people that may need a little extra help such as the elderly and those with small children by phone or in person if it is safe to do so.
· When walking outside after an ice storm use extreme caution to avoid slips and falls.
