Storm/Severe Weather Coordination Message #1 – Friday Evening 11/9/18-Saturday Afternoon 11/10/18 Heavy Rainfall/Strong Wind/Severe Weather Potential
Hello to all…
..Heavy Rainfall and the potential for strong to damaging winds including isolated strong to severe thunderstorms that can bring stronger winds down to the surface expected Friday Night into Saturday Morning with strong winds possible across the coverage area during Saturday Afternoon and Evening..
..A Flood Watch is now in effect from Friday Afternoon into Saturday Afternoon for the entire NWS Boston/Norton coverage area except for Cape Cod and the Islands for widespread 1-2″ of rainfall with isolated higher amounts to 2.5″ possible. Given the wet weather pattern and additional rainfall, this will potentially lead to urban and poor drainage flooding as well as the potential for small river and stream flooding..
..SKYWARN Self-Activation will monitor the strong to damaging wind and flood potential for late Friday Afternoon through Saturday Afternoon..
Another dynamic storm system will swing through Southern New England Friday Night into Saturday. It will bring heavy rain across the NWS Boston/Norton coverage area late Friday Afternoon into early Saturday Morning as well as the potential for strong to damaging winds in two phases. The first phase of winds with the heavy rainfall and any thunderstorm activity Friday Evening into early Saturday Morning with the strongest winds centered across Southeast Massachusetts and Rhode Island. The second phase of the strong winds will affect the region Saturday Afternoon into the early evening as the storm swings through the region and those winds could affect much of the NWS Boston/Norton coverage area. These winds are not expected to be quite as strong as last Saturday but will have the potential for isolated pockets of tree and wire damage and isolated power outages. Heavy rainfall may produce flooding given the wet pattern of the last 6 weeks and there could be localized higher amounts that enhance flooding in some areas. Urban and poor drainage flooding may also be a greater issue due to leave clogged storm drains.
Any thunderstorms with the heavy rainfall may have the potential to enhance the strong to damaging winds reaching the surface Friday Night. This potential will be monitored closely.
SKYWARN Self-Activation will monitor the strong to damaging wind and flood potential for late Friday Afternoon through Saturday Afternoon. Another coordination message will be posted by 10 AM Friday Morning. Below is the NWS Boston/Norton Flood Watch Statement, Hazardous Weather Outlook and Enhanced Hazardous Weather Outlook:
