Riverside commuters might want to set aside some extra time for tomorrow's evening comute

A.M. UPDATE: The river actually dropped overnight, but as of 5:45 a.m., was rising again and was back to 11.5 feet.

USGS data shows the Muddy River rapidly climbing the height ladder today. If it gets to 15 feet, the MBTA will haul out the large wooden boards and the sandbags and blockade the tunnel the Riverside Line uses to get into and out of Kenmore station.
