Across northern Maine, snow accumulations of 12-16 inches with locally higher amounts in excess of 20 inches are forecast.
In addition to the snow, winds will range 55-65 mph along the coast. Further inland, winds will range 25-35 mph, allowing for blowing snow and reduced visibilities. Snow will taper off across the region on Wednesday.

Thunderstorms for Southern Florida on Monday
A cold front over central Florida will continue to track southeastward through the day toward the Florida Keys and Bahamas. Ongoing showers and thunderstorms ahead of the front will continue all day. Southerly winds will bring warm moist air northward across much of southern Florida. In addition, some breaks in the clouds later this morning and early afternoon should be enough for some instability to build. With strong wind shear in place, ongoing thunderstorm activity is forecast to increase in intensity with some of these storms becoming strong to severe. Large hail and damaging winds will be the primary hazards with any of the stronger storms.
