A strong Nor'easter off the Mid-Atlantic and Northeast will bring coastal flooding, rip currents, strong wind gusts, and heavy rain to the region through Monday evening... ...There is a Moderate Risk (level 3/4) of excessive rainfall over parts of the Southwest, Great Basin, and Central/Southern Rockies on Monday and the Southwest, Southern Rockies, and Southern High Plains... ...There is a Slight Risk (level 2/4) of excessive rainfall over parts of Southern New England on Sunday and the Upper Midwest on Monday... An upper-level low along the Mid-Atlantic Coast will move northeastward into the Gulf of Maine by Tuesday. The powerful Norâ€easter is currently drifting near the New Jersey coastline and continues to bring coastal impacts and unsettled weather from the Mid-Atlantic to New England through Monday. Conditions will gradually ease Sunday afternoon into early this week. Furthermore, widespread minor to moderate coastal flooding is expected for at least one more high-tide cycle Sunday morning. This follows prior significant coastal flooding impacts on Saturday, which affected numerous locations along the Mid-Atlantic and Northeast coastlines. In addition, strong rip currents, rough surf, and significant beach erosion will make for dangerous beach conditions from the Carolinas and Mid-Atlantic into southern New England through at least Sunday evening. Moreover, strong wind gusts up to 40-50 mph remain possible Sunday morning from New Jersey to Long Island, which may lead to additional power outages and tree damage. Heavy rain may also lead to isolated inland flooding from Northern New Jersey into Southern New England through Monday. Also, the Norâ€easter will produce significant coastal impacts along the Northeastern Seaboard. The storm will produce heavy rain over parts of New England. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of Southern New England on Sunday into Monday morning. The associated heavy rain will create mainly localized flash flooding, with urban areas, roads, small streams, and narrow canyons/gullies the most vulnerable. The heavy rain associated with the storm will slowly wane to a few showers over parts of Maine by Tuesday morning. Please see the latest WPC Key Messages for this system at wpc.ncep.noaa.gov. In the meantime, tropical moisture from the Pacific will stream into the Southwest, producing widespread showers and thunderstorms with heavy rain. Therefore, the WPC has issued a Moderate Risk (level 3/4) of excessive rainfall over parts of the Southwest, Great Basin, and Central/Southern Rockies for Monday. The Moderate Risk (level 3/4) of excessive rainfall will expand into the Southern High Plains on Tuesday. Also, a wave of low pressure over parts of the Northern Plains on Monday will produce showers and thunderstorms with heavy rain over parts of the Upper Midwest on Tuesday. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Upper Midwest. The associated heavy rain will create mainly localized flash flooding, with urban areas, roads, small streams, and narrow canyons/gullies the most vulnerable. Additionally, a Slight Risk (level 2/4) of excessive rainfall will extend into parts of the Central Plains and Middle Mississippi Valley on Tuesday.
