Good afternoon, Following is an updated briefing regarding the expected periods of heavy rainfall for tonight into early Tuesday morning. *Significant Changes Since Last Briefing*: - *Flood Watch Expanded into Much of Rhode Island, In Effect Monday Morning to Tuesday Morning.* - *Increased Storm Total Rain Amounts, especially into western MA and CT.* - *Expansion of WPC's Moderate Risk Excessive Rain Outlook valid for Monday into portions of Rhode Island.* Showers and thunderstorms producing heavy rain are ongoing across eastern NY and into western sections of CT and MA. These rains will shift northeast this evening and overnight with the greatest risk for excessive rainfall capable of flash flooding tonight mainly into the Berkshires and into western sections of CT and MA, and will be ongoing into Monday night. Heavy to locally excessive rains capable of flash flooding are then expected to develop eastward into central MA and RI on Monday, with a more limited risk for flooding of urban and poor drainage areas into eastern MA. The greatest risk for SIGNIFICANT flooding is in interior western sections of MA and CT. Larger rivers and smaller streams are expected to rise in the face of heavy rains tonight into Tuesday. The most significant rises are anticipated in interior western New England, and river levels may remain elevated after cessation of heavy rains. Rivers that are potentially at risk of reaching or exceeding bankfull include the Connecticut, Housatonic, Hoosic, Westfield, Deerfield and Farmington River basins. River Observations and Forecasts can be monitored at the Northeast River Forecast Center webpage linked here: Northeast River Forecast Center <https://www.weather.gov/nerfc/> Expect our next update by 600 AM Monday.

Good morning, Please find attached an updated one page briefing regarding expected periods of heavy rainfall beginning this afternoon and continuing through early Tuesday morning. Since yesterday's briefing *confidence has increased that the greatest threat for excessive rainfall will be across western MA/CT where widespread 2 to 4 inches of rainfall is forecast to fall between this afternoon and early Tuesday morning. Locally higher amounts of 5+ inches will be possible over this area as well. * There remains a moderate risk for excessive rainfall/flash flooding across western MA with the rest of southern New England in a slight risk category. No changes have been made to the existing flood watch. See the attached graphics for more details. We'll provide another update later this afternoon when new information becomes available.

[07.08.2023 PM] NWS Boston EM Briefing - Excessive Rain Sunday into Early Tuesday Morning
by BOX Operations - NOAA Service Account 08 Jul '23

08 Jul '23

Good afternoon, 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. A Flood Watch has now been issued for CT and western and central MA. The Watch start and end times are: - *Southern CT: *Sunday evening through Monday Afternoon - *Litchfield County in CT: * Sunday Afternoon through Monday Evening - *Hartford, Tolland and Windham Counties in CT: *Sunday Evening through Tuesday Morning - *Berkshire County in MA: * Sunday Afternoon through Monday Evening - *Franklin, Hampden, Hampshire, Worcester and Northern Middlesex County in MA: *Sunday Evening through Tuesday Morning. 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. *The Flood Watch may need to be expanded eastward into remaining portions of MA and RI in later updates* . 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. 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. Attached supporting graphics include the following: - One-page briefing. - A map which shows the Flood Watch area. - Forecast storm total rainfall (note: locally higher amounts are possible). - Excessive Rain Outlooks for Sunday and Monday from the Weather Prediction Center, highlighting the risk for excessive rains. - 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. Expect the next briefing to be sent by 600 am Sunday. Thank You!

[07.07.2023 PM] NWS Boston EM Briefing - Excessive Rainfall Expected Sunday and Monday
by BOX Operations - NOAA Service Account 07 Jul '23

07 Jul '23

Good afternoon, Following is the latest briefing regarding the potential for excessive rainfall for Sunday and Monday. Confidence continues to grow on the potential for heavy rain for Sunday and Monday. This risk currently appears more focused in central and western sections of CT and MA on Sunday, then shifting eastward into most of Southern New England for Sunday night and Monday. A Flood Watch may need to be considered for Sunday and/or Monday, due to the potential for excessive rainfall producing urban and poor drainage flash flooding and rises on rivers and smaller streams. The location and amounts of previous days' rain will influence that decision, along with specific rain amounts, both of which are still too uncertain at this time. Expect another update to to this briefing no later than 6 AM Saturday morning. Thank You!
