<div dir="ltr"><div>Good afternoon, </div><div><br></div><div>Following is an update regarding excessive rain forecast for late in the day Sunday, lasting into early Tuesday morning. There have been several changes with this afternoon's forecast.</div><div><br></div><div>A Flood Watch has now been issued for CT and western and central MA. The Watch start and end times are: </div><div><ul><li><b>Southern CT: </b>Sunday evening through Monday Afternoon </li><li><b>Litchfield County in CT: </b>
Sunday Afternoon through Monday Evening</li><li><b>Hartford, Tolland and Windham Counties in CT: </b>Sunday Evening through Tuesday Morning</li><li><b>Berkshire County in MA: </b>
Sunday Afternoon through Monday Evening</li><li><b>Franklin, Hampden, Hampshire, Worcester and Northern Middlesex County in MA: </b>Sunday Evening through Tuesday Morning.<b> </b></li></ul></div><div>Multiple rounds of showers and thunderstorms producing heavy rainfall are anticipated Sunday into Monday night. The focus for heaviest rains Sunday into Sunday night is in interior western New England, generally from Worcester westward. Heavy rains then spread eastward Monday into Monday evening across much of Southern New England. <i>The Flood Watch may need to be expanded eastward into remaining portions of MA and RI in later updates</i>. </div><div><br></div><div>The risk for excessive rains capable of localized flash flooding continues to increase. The Weather Prediction Center has included portions of interior Southern New England in a Moderate Risk for excessive rain. This level of excessive rain risk is uncommon for Southern New England, and speaks to the potential for heavy rain capable of flash flooding. </div><div> <br></div><div>Rises on larger rivers and smaller creeks and streams are expected to occur during and after cessation of heavy rains. While there are no rivers forecast to reach into flood stage, our partners at the Northeast River Forecast Center are monitoring river levels in interior Southern New England, particularly the Connecticut River basin. This is highlighted in the Significant River Flood Outlook, which is attached. </div><div><br></div><div>Attached supporting graphics include the following: </div><div><ul><li>One-page briefing. </li><li>A map which shows the Flood Watch area.</li><li>Forecast storm total rainfall (note: locally higher amounts are possible). </li><li>Excessive Rain Outlooks for Sunday and Monday from the Weather Prediction Center, highlighting the risk for excessive rains. </li><li>5-Day Significant River Flood Outlook from the Northeast River Forecast Center, bringing awareness that river levels exceeding flood stage are possible in the yellow-highlighted area on the graphic.</li></ul></div><div>Expect the next briefing to be sent by 600 am Sunday.</div><div><br></div><div>Thank You! </div><div><br></div><div>Meteorologists: Andrew Loconto, Bill Leatham and Kyle Pederson</div><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div><span style="color:rgb(0,0,0);font-size:small">If you have any questions or would like more information, </span><span style="color:rgb(0,0,0);font-size:small">don't hesitate to contact us via this email address, on </span><a href="https://nwschat.weather.gov/" style="font-size:small" target="_blank">NWSChat</a><span style="color:rgb(0,0,0);font-size:small">, or at the following:</span></div><font size="2"><span style="color:rgb(0,0,0)"><div><span style="color:rgb(0,0,0)"><br></span></div>National Weather Service Boston/Norton, MA</span><br style="color:rgb(0,0,0)"><span style="color:rgb(0,0,0)">46 Commerce Way</span></font></div><div dir="ltr"><font size="2"><span style="color:rgb(0,0,0)">Norton, MA 02766</span></font><div><font size="2">508.622.3280<br style="color:rgb(0,0,0)"></font><a href="http://www.weather.gov/boston" style="color:rgb(17,85,204);font-size:small" target="_blank">Website</a><span style="font-size:small"> | </span><a href="http://www.facebook.com/NWSBoston" style="color:rgb(17,85,204);font-size:small" target="_blank">Facebook</a><span style="font-size:small"> | </span><a href="http://www.twitter.com/NWSBoston" style="color:rgb(17,85,204);font-size:small" target="_blank">Twitter</a></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>
