Right now
The most recent data we hold from NOAA arrived 8 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
3 other detections within 20 km in the last 24 hours, the nearest 23 km from here.
This alert expired on 13 July 2026 at 02:45 UTC. It is kept here as a record.
No stronger detection stands among the 24 recorded within 20 km of this point since 17 June 2026 — 11 others scored the same. The last comparable one was on 17 June 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.
