Original Post:

Good morning, commuters! We’ll be keeping an eye on the roads and rails this morning, reporting any delays or issues — and 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.

After pleasant weather for a few days, things take a turn for the unpleasant today, according to the Capital Weather Gang. That means it will be cold and wet. This morning, rain is expected to move from west to east between 7 and 9 a.m.

So far:

— A sinkhole has closed westbound Annapolis Road/MD 450 at Route 1 in Bladensburg. The closure will remain through the morning rush hour, so use alternate routes and expect major delays approaching that spot. This is just east of the Maryland-Washington border.

— There are delays on the Orange Line heading to New Carrollton after an earlier train malfunction at Vienna.
