Right now
The most recent data we hold from NOAA arrived 32 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
One other detection within 20 km in the last 24 hours, <1 km from here.
This alert is in force until 19 September 2026, 16:15 UTC.
It is the 44th strongest of the 57 detections recorded within 20 km of this point since 12 March 2026. The last comparable one was on 17 August 2026.

Safety Information
During flooding: never walk, swim, or drive through floodwaters. Six inches of moving water can knock you down, and one foot of water can sweep away a vehicle. Move to higher ground if waters rise. After flooding, avoid contact with floodwater which may contain sewage, chemicals, or debris. Follow local emergency service guidance.
