#HappyNewYear to you all! Ten years ago, the “Super-Outbreak of 1974” was the undisputed peak of severe weather disasters in the U.S. Then, 2011 happened. Born out of tragedy, and a drive to ensure it never happens again, @NWS is building a #WeatherReadyNation. weather.gov/wrn

11pm #Dorian update:
Satellite imagery indicated that the cloud pattern associated with Dorian was a little better organized with a clear eye surrounded by a ring of very deep convection. Life-threatening storm surge and dangerous winds are expected along portions the coasts of Georgia, South Carolina, and North Carolina, and portions of southeast Virginia and the southern Chesapeake Bay, regardless of the exact track of Dorian's center.

(Thread) The official start of Spring - the Spring/Vernal Equinox - is today, at 5:58 PM EDT. This marks the time when the day-to-night line, called the terminator, is perfectly vertical from pole to pole. #SpringEquinox #FirstDayOfSpring The Vernal Equinox is also the day of the year when day and night are most nearly equal everywhere on earth.
There will be more daylight than nighttime each day now, until the Fall/Autumnal Equinox in September.
