Severe Weather
Right now
The most recent data we hold from NDBC arrived 29 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
10 other detections within 20 km in the last 24 hours, the nearest <1 km from here.
Reported by NDBC today.
It is the 63rd strongest of the 76 detections recorded within 20 km of this point since 8 March 2026. Another comparable one was recorded here earlier the same day. 11 more were recorded here in the fortnight before it.
