Ice accumulation chart

The ice should be about an inch thicker than yesterday. As explained below there are a number of reasons why 'your results might vary'. Even a thin layer of snow or thick frost will dramatically slow the growth rate. As always, check the ice itself to see what the ground truth is. 27 mm(1.06") ice: Not quite enough to stay on top.

The plots and color-coded maps are chosen to provide information about the current state of the sea ice cover and how the most current daily data available compare with the record lows and record highs for the same date during the satellite era. Sea ice concentration is the percent areal coverage of ice within the data element (grid cell). The ice should be about an inch thicker than yesterday.

As always, check the ice itself to see what the ground truth is. 27 mm(1.06") ice: Not quite enough to stay on top. The deposits of ice are called glaze. Glaze is not snow or sleet. If you receive freezing rain only, then you melt what lands in your gauge and report that as your daily precipitation amount. You report the new snow amount to be 0.0 However, the entry for "Total Depth of Snow" includes the depth of both snow (new and old) AND ice. 4-6 Inches – Ice fishing, foot travel in single-file lines, and small spaced seating on the ice should be safe, presuming the ice is clear and clean. 6-10 Inches – Snowmobiles and ATV’s can travel safely on good ice that is over inches thick.

Sea ice extent is derived from sea ice concentration. Images are not available for the average or standard deviation. When reusing Charctic images or data, please credit “National Snow and Ice Data Center.” Check ice thickness at least every 150 feet. Temperature, snow cover, currents, springs and rough fish all affect the relative safety of ice. Ice is seldom the same thickness over a single body of water; it can be two feet thick in one place and one inch thick a few yards away. Check the ice at least every 150 feet. The charts below depict the probability of freezing rain reaching or exceeding 0.25 inch for Days 1-3. The following charts depict in a 4-panel format the final forecast of the probabilities of snow reaching or exceeding 4, 8, and 12 inches and the probability of freezing rain reaching or exceeding 0.25 inch. where is the deepest snow (col. 1) how much did it snow in the last 24 hours (col. 2) what is the snow forecast (col.3).

If it is cloudy and there is a 10 mph wind the temperature will have to be 27 degrees F to grow 1/3" of ice in 12 hours. This assumes there is a layer of ice on the water that is thick enough to fend off the 10 mph wind. If you have clear skys, cold temperatures (15 deg F) and wind (15 mph)

Lake Pepin ice thickness measurements typically start in mid-February and are conducted on a weekly basis. Measurements are reported from each mile on the Upper Mississippi River between mile 765 and 786.

The Sperry–Piltz Ice Accumulation Index, or SPIA Index ™, is a forward-looking, ice accumulation and ice damage prediction index that uses an algorithm of researched parameters that, when combined with National Weather Service forecast data, predicts the projected footprint, total ice accumulation, and resulting potential damage from Ice thickness measurements are generally taken near the beginning of the month from October to June. Readings taken near the end of the month are appied to the following month. If it is cloudy and there is a 10 mph wind the temperature will have to be 27 degrees F to grow 1/3" of ice in 12 hours.

icedepth. Created and inspired by my own personal passion to ice fish, to bring safety amongst the ice fishing community and anyone who wants to venture out onto the ice. I wanted to create a website that would house a list of fishable Minnesota lakes where users can input how much ice there is on them. Once users input data for a specific lake
