A <a href=\"https:\/\/mesonet.agron.iastate.edu\/timemachine\/?product=59&amp;timestamp=202604141735\" rel=\"nofollow noopener\" target=\"_blank\">flood watch<\/a> spanned the entirety of both the upper and lower peninsulas as rain continued to fall in mid-April.<\/p>\n<p>Flooding along the Grand River\u2014Michigan\u2019s longest\u2014near Grand Rapids is visible in the image above (right), acquired on April 11, 2026.

The images are <a href=\"https:\/\/science.nasa.gov\/earth\/earth-observatory\/how-to-interpret-a-false-color-satellite-image\/\" rel=\"nofollow noopener\" target=\"_blank\">false-color<\/a> to better distinguish water from vegetation and other land cover.<\/p>\n<p>At the time of the 2026 image, <a href=\"https:\/\/water.noaa.gov\/gauges\/CMPM4\" rel=\"nofollow noopener\" target=\"_blank\">river gauge data<\/a> showed the Grand River at Comstock Park was in minor flood stage. The river had crested on April 8 at about half a foot beneath the major flood level at this gauge, making it one of the <a href=\"https:\/\/www.fox17online.com\/weather\/weather-articles\/grand-river-forecast-to-reach-major-flood-stage-near-comstock-park\" rel=\"nofollow noopener\" target=\"_blank\">harder-hit locations<\/a> along the river. Water had already submerged roads and trails along its banks and encroached on homes, according to <a href=\"https:\/\/www.woodtv.com\/news\/kent-county\/in-comstock-park-grand-river-nears-major-flood-stage\/\" rel=\"nofollow noopener\" target=\"_blank\">news reports<\/a>, and more water was still to come. After another round of rain, the river was <a href=\"https:\/\/water.noaa.gov\/gauges\/GDRM4\" rel=\"nofollow noopener\" target=\"_blank\">rising again<\/a> as of April 16, with the potential to reach one of the <a href=\"https:\/\/wgrd.com\/grand-river-flood-history\/\" rel=\"nofollow noopener\" target=\"_blank\">highest levels on record<\/a> in Grand Rapids.<\/p>\n<p>The area has been beset by many weeks of soggy weather. Grand Rapids saw <a href=\"https:\/\/www.weather.gov\/wrh\/climate?wfo=grr\" rel=\"nofollow noopener\" target=\"_blank\">approximately double<\/a> the normal March rainfall totals in 2026. In the first half of April, it received 5.79 inches (147 millimeters), exceeding the average for the entire month by nearly 2 inches.<\/p>\n<p>The story is similar throughout the state. To the north, where an above-normal snowpack still covered the ground, abundant rainfall combined with melt to amplify flooding. Floodwaters in the northern Lower Peninsula washed out roads, including part of a <a href=\"https:\/\/www.cbsnews.com\/detroit\/news\/part-of-m-119-tunnel-of-trees-washed-out-emmet-county\/\" rel=\"nofollow noopener\" target=\"_blank\">scenic drive<\/a>, and rendered airport <a href=\"https:\/\/bridgemi.com\/quality-life\/dam-threatened-airport-closed-roads-wash-out-amid-northern-michigan-rains\/#:~:text=too%20much%20water%20on%20the%20runway\" rel=\"nofollow noopener\" target=\"_blank\">runways unusable<\/a>. The buildup of water has also stressed dams around the state.
