PREVIOUS BRIEFING
An impactful storm will move in with heavy rain looking probable. In addition to the heavy rain, there is the potential for gusty winds, coastal flooding, and dangerous conditions on the waters. The latest information regarding the system is below:
- Heavy Rain: A widespread 1 to 3 inches of rain is possible resulting in the potential for flash flooding and flooding of some creeks and streams. The Weather Prediction Center has our region outlooked in a MARGINAL (1/4) risk for excessive rainfall (Graphic 1).
- Winds: Easterly gusts of 30-40 MPH are possible on land Sunday Night (Graphic 2) and Monday (Graphic 3), with locally higher gusts along the immediate coast. On the waters, a period of gale force gusts and dangerous seas are likely. Extra precautions may need to be considered with any outdoor holiday decorations up.
- Coastal Flooding: With strong onshore flow, water will begin to pile up along the coast and within the back bays of coastal communities. It still too early to know which locations may see the greatest impacts and what magnitude, if any, the flooding may reach.
Confidence is high in this being an all rain event. Confidence is lower in the specifics and magnitudes of impacts as this depends on the track of the storm and the intensity.
