Hello to all…

Rainfall closer to the 2″ range is expected in eastern areas with the heavier rainfall of up to 4″ with isolated higher amounts more likely over portions of the Connecticut River Valley and the eastern slopes of the Berkshires. This amount of rainfall and any higher amounts in thunderstorms could cause flooding of urban and poor drainage areas and smaller rivers and streams..

The potential exists for a significant coastal storm to affect Southern New England Sunday Afternoon into Monday Afternoon. The headlines of this coordination message detail the latest information. Key items that will bear watching as we get closer to this storm system’s impacts include the following:
1.) Exact track of the coastal system. Some models are indicating a track up the Hudson River Valley or Western New England while other models are closer to Eastern New England. This will affect where the heaviest rainfall occurs and how widespread the damaging wind threat is in the region.
2.) How quickly the storm system intensifies as it tracks into and north of the region. This will also affect the rainfall/flooding and damaging wind impacts.
3.) Influence of Potential Tropical Cyclone 18 and how much moisture and energy from this system interacts with the coastal storm and its explosive development.
As we get closer to the event, the configuration of watches will be changed based on the above 3 factors.
SKYWARN Activation is likely Sunday through Monday. SKYWARN Self-Activation will monitor the storm from Sunday morning through mid-afternoon with Ops at NWS Taunton likely centered around Sunday Afternoon into early Monday Morning followed by self-activation monitoring into Monday Afternoon for continued threat of strong winds. Another coordination message will be posted by 1130 PM this evening.
