Trails should be good now, but the trailhead is closed along with the end of Tester Rd. Still 2 feet of water on Tester that'll probably drain by noon-ish, but parks might be slower to open the trailhead.
Old Snohomish Monroe Road is open through Monroe and way past the risk of flooding at this point. Still closed from Snohomish side. https://snoco-gis.maps.arcgis.com/apps/webappviewer/index.html?id=15578784822345459c008d66ed1253ab
