HYDROMETEOROLOGICAL OUTLOOK FOR THE NEXT 2 WEEKS:

New England has been under a persistent weather pattern which has
featured recurring coastal storms producing bouts of heavy rain,
significant runoff and strong onshore winds. Rainfall across eastern
Massachusetts, coastal New Hampshire and southwestern Maine for the
month of March is a remarkable 5 to 9 inches above normal to date
(<http://www.erh.noaa.gov/nerfc/watersupply.shtml>http://www.erh.noaa.gov/nerfc/watersupply.shtml).
River flows in this same region are well above normal based on the
latest USGS Streamflow percentile data
(<http://waterwatch.usgs.gov/>http://waterwatch.usgs.gov/).

The prevailing pattern for the past several weeks is forecast to
break down late next week but not before one more system affects the
region. Another strong slow moving coastal storm is forecast in the
Monday-Wednesday time frame next week is it becoming increasingly
more likely that it will produce an extended period of strong onshore
winds, heavy rainfall and enhanced runoff
(<http://www.hpc.ncep.noaa.gov/qpf/day1-5.shtml>http://www.hpc.ncep.noaa.gov/qpf/day1-5.shtml).

By April 1st, the weather pattern will change significantly and
should begin to feature high pressure along the east coast through
about April 5th or 6th. This regime will bring generally dry weather
and a period of light mostly offshore winds from the west and
southwest through approximately April 6th.
