2019 Precipitation in Minnesota

2019 was another banner year for precipitation in Minnesota, with over 20 individual annual precipitation records set, and the state turning in its wettest year on record.

Precipitation totals for the year exceeded 30 inches over all but about 5-10% of the state, mainly in far northern Minnesota, with totals exceeding 50 inches in parts of southern and southeastern Minnesota. Well over half of the state was 12-20 inches (or 50-70%) wetter than normal. Annual surpluses of that magnitude over such a large area contributed to 2019 being Minnesota's wettest year on record, on a statewide-average basis, with an average of 35.51 inches. This eclipsed the old record of 33.93 inches, set in 1977.

Although no climate observing station was able to break the statewide individual annual precipitation record of 60.21 inches set by Harmony in 2018, many stations with over 50 years of observations did break their own annual precipitation records. Rochester International Airport led the pack with 55.16 inches, breaking its old record by more than 11 inches.

The Twin Cities International airport, part of the longest station history in the state, had just broken its record in 2016, but broke it again in 2019, with 44.17 inches. Other records fell throughout the state. The majority of these stations broke records that had been set this decade.

Even closer to home, the ACD has utilized the precipitation data collected by our volunteer observers to assist with putting our monitoring well data in context. We have observed sustained wetland hydrology because of the abundance of precipitation. How this will affect how wetlands are managed in the present and future will need to be addressed by the current wetland regulatory rules and by utilizing the data we collect when reviewing wetland delineations.

Tips for Staying Safe in Winter

 De-icing salt is so common here in snowy Minnesota, we hardly even think before tossing it down. But we really should be thinking hard because all that salt accumulates in local streams, lakes, and wetlands causing stress and sometimes death to native animals and vegetation. Salt dissolves easily in water which means it's almost impossible to remove without expensive and time-consuming treatment. Road and sidewalk safety is a priority for all of us, so what is an environmentally conscious Minnesotan to do if they want to stay safe and minimize their salt use? Here are some tips!

Shovel First. Shovel and scrape sidewalks before they are walked on so ice doesn't have a chance to form in the first place.

Choose the Right Salt. Different chemicals work at different pavement temperatures. Be sure to choose the right one for the conditions. Sodium chloride, the most common de-icer, will only work when the pavement temperature is above 15 degrees F.

Scatter Salt Grains. Granular salt melts ice fastest when the grains are spread 3 inches apart. Contrary to popular belief, adding more salt will actually make the ice melt slower!

Sweep up Excess. If there is salt left on the ground after all the ice is gone, sweep it into a bucket to use in the next storm. You paid for it so don't let it wash away!

Pre-treat Pavement. Applying a liquid de-icer to pavement 24-48 hours before a storm will help prevent ice from adhering to the surface and make it a lot easier to scrape up.

Wear Proper Footwear. Boots with extra traction such as cleats or spikes reduce the risk that you may slip and fall. They are a worthwhile investment here in Minnesota where we're bound to encounter ice at some point.

Avoid Distractions. We all know not to drive while we're distracted. The same goes for walking! Avoid using cell phones while walking and keep your eyes on the path in front of you.

Drive for the Conditions. Here in Minnesota, there is no escaping the snow and ice. Remember that you are ultimately responsible for your own safety, so always drive with caution.

Do the Penguin Shuffle. Always anticipate icy conditions and keep yourself safe by walking on marked paths near handrails.

If you See Something, Say Something! As an environmentally conscious Minnesotan, one of the best things you can do to combat chloride pollution in our waters is to talk to your friends, neighbors, and local businesses. Pressure from residents like you can help turn the tide and protect our valuable freshwater resources now and for many generations to come.
