Spring outdoors: equinox + blooms
The vernal equinox lands March 20 at 10:46 a.m. EDT, promising nearly equal day/night and an uptick in outdoor activity — forecasters say this year's equinox could bring especially bright auroras for northern‑latitude viewers ( ). National parks are primed for spring blooms and cherry‑blossom peaks are forecast for D.C., but Yellowstone already logged its first grizzly sighting of spring — a reminder to follow wildlife safety rules ( ).
NOAA’s Space Weather Prediction Center has a G2 (moderate) geomagnetic-storm watch for March 19 and predicts a G1 (minor) storm for March 20 tied to CMEs that left the Sun on March 16, with modeled solar‑wind speeds around 500 km/s. (swpc.noaa.gov) Forecasts tied to that activity say auroras could be unusually visible south of their typical zones this week, with some outlets reporting the display could reach as far into the continental U.S. as 19 states. (usatoday.com) The National Park Service projects Washington, D.C.’s Tidal Basin peak bloom window for 2026 at March 29–April 1 and notes once peak begins blossoms typically remain for seven to 10 days. (nps.gov) The NPS also says a restoration of the Tidal Basin and West Potomac Park seawall—budgeted at $113 million—is finishing early and that walkways between the Jefferson Memorial and the FDR Memorial will remain closed through the bloom period with alternate routes provided. (nps.gov) Parks experts point to a coast‑to‑coast bloom season: Great Smoky Mountains hosts more than 1,500 flowering species with lower‑elevation spring peaks in mid‑to‑late April, while desert parks like Death Valley are reporting superbloom conditions after an unusually wet winter. (gearjunkie.com) Yellowstone biologists reported the park’s first grizzly sighting of spring on March 9 — the bear was observed scavenging a bull bison carcass — and the NPS reminded visitors that approaching bears within 100 yards is prohibited and that carrying bear spray and reporting sightings to rangers are standard safety requirements.
