Chelmsford MA: we are on the edge of the "slight" to "moderate" risk areas for excessive rainfall later this evening as the remnants of Ida pass through, which means possible sudden street flooding. Drive cautiously this evening. South of us, especially in the NYC region, the flash flooding risk is a rather unprecedented "high". Forecast discussion details: "Signals remain strong for potentially deadly and damaging flash flooding from parts of the Mid-Atlantic region across southern New York into the southern portion of New England today and tonight...especially across highly urbanized metropolitan areas and areas of steep terrain...later today as Tropical Depression Ida moves through the area. The latest WPC QPF guidance maintained areal average rainfall amounts of 3 to 8 inches with isolated higher amounts from western Maryland and Pennsylvania northeastward across southern New York and into the southern portion of New England. High resolution guidance continues to support higher amounts embedded with this area...with amounts in excess of 8 inches still in the realm of possibility."
