NOTICE: Notifications Timeline Disruption

SWPC is transitioning to a new internal alerting system to modernize how we generate and deliver space weather products.

During this transition, a small subset of watches, warnings, and alerts (WWAs) are not being displayed on the graphical Notifications Timeline and so it should not be used as the sole source for real-time situational awareness.

For the most accurate reflection of active space weather products, users should consult the text-based listing of all WWAs here.

Our engineering teams are actively addressing the error, and this issue is expected to be resolved shortly.
