Good morning, commuters! Wednesday’s rain was problematic enough for travelers, but the water will continue to cause problems into Thursday morning’s rush hour. There will be some additional rain today as well, but flooding and standing water will continue to slow commuters on the roads and rails alike. Add some extra time to your commute, because as we have seen all week, rain invariably causes problems and delays for travelers.
Remember: Don’t try and force your car through a flooded roadway. If you come to a flooded spot in the road, turn around and find an alternate route.
We’ll be keeping an eye on the roads and rails this morning, reporting any delays or issues. We will need your help: If you hear about any congestion, delays, problems or anything at all, tell us in the comments section below or by tweeting @drgridlock.
