The Fall/Autumnal Equinox is TODAY at 2:19 PM EDT. That's the time at which our Sun is directly over the Earth's equator, signaling the start of Northern Hemisphere astronomical fall. The Earth’s northern hemisphere will continue to tilt further from the sun through the Winter Solstice on Dec 21.

We're at T-minus 4 days & counting until the SWFOL1 launch! 🚀

NOAA's #SWFOL1 🛰️ will improve #SpaceWeather forecasting:

Its magnetometer will track solar plasma heading toward Earth and help forecast geomagnetic storms.

Tropical Storm Kiko will continue to pass north of the Hawaiian Islands today and Wednesday, disrupting the trade winds, producing areas of heavy rainfall, and generating large surf along east facing shores. Find more detailed info at the NWS Forecast Office Honolulu's webpage: weather.gov/hfo

A day at the beach won't be "a day at the beach" today. Higher than normal tides and persistant onshore winds are leading to rough surf, rip currents, and coastal flooding up and down the U.S. East Coast. Take extra precautions while enjoying the coast today.

After a fairly cool stretch of weather for portions of the U.S., temperatures will be on the rise this week. That trend will continue into mid September. The exception being eastern portions of the country with a near to below normal signal. Here's the 8-14 day temperature outlook (Sept. 15-21).👇

It is a chilly morning across the eastern third of the country today! In fact, as of 8 am ET, seven stations recorded a record low with with many more tied or within 3 degrees of the previous daily record.

☀️Ample sunshine will allow for a quick warmup by this afternoon.

Unseasonably cool weather across the Plains and into the Midwest today will push even further south and east behind a cold front as we move into Saturday. Above normal readings are set to return to much those same areas by mid-week next week. Get the latest at weather.gov
