Hydrologic Outlook

Issued at 13:22 Friday 20 September 2019
Summary

Several rounds of heavy rain this weekend are likely to affect
most of Lower Michigan, with the heaviest round of rain likely
moving in Sunday evening. The main threat is for short-duration
flooding in areas of poor drainage/low spots, as well as on some
of the smallest streams. The larger rivers will see significant
rises by early next week, but none are expected to cause flooding.

At this time it looks like the heaviest rain will fall along and
west of US-131, but all locations will likely see at least one
round of significant rain. Areas along the lakeshore between
Holland and Muskegon saw the highest rain totals last week as
well, which means the soils there are still quite wet, and
additional heavy rain will have a harder time absorbing into the
ground.

Stay informed with the latest forecasts and information at
www.weather.gov/grr and remain alert for ponded water this
weekend, especially if driving at night.
