NOAA Weather Alerts
noaa-alerts // score
The US is currently under 192 active weather alerts, but at a lower intensity level than typical for this time period — the alert score of 419 sits noticeably below the expected 659, meaning fewer extreme or severe warnings are in effect compared to the historical average. This is considered normal for the short term, though it represents a mild decline from recent activity. Real-world impact: while severe weather remains a concern in some regions, the overall threat level across the country is currently moderate rather than elevated, which typically means fewer hurricane warnings, tornado watches, or widespread winter storm alerts than would normally be expected.
Weighted active US weather alert score via NOAA (Extreme/Severe/Moderate)
NOAA weighted alert score 421, within normal range for US weather activity
NOAA alert score 421, reduced vs expected 654
NOAA weighted alert score 420, within normal range for US weather activity
NOAA alert score 421, reduced vs expected 656
NOAA weather alert score declined to 419 from expected 659, dropping 1.47 standard deviations below normal and transitioning from drift to normal status despite 192 active alerts. Both short and long-term indicators confirm stabilization within typical ranges, suggesting reduced severity concentration across current US weather threats.

NOAA alert score 1101, elevated vs expected 544
NOAA weighted alert score 1129, within normal range for US weather activity
NOAA alert score 1157, elevated vs expected 531
NOAA weather alert score increased to 1148 from expected 626 (1.40x), driven by 593 active alerts now pushing into drift territory long-term (1.95 score) despite remaining within normal short-term bounds. The elevation above the long-term band ceiling of 1160.84 signals sustained severe weather activity warranting monitoring for sustained drift conditions.
NOAA alert score 1209, elevated vs expected 525
NOAA weighted alert score 1196, within normal range for US weather activity
NOAA alert score 1289, elevated vs expected 574
NOAA alert score 1344 — significantly elevated, potential major weather event across the US
NOAA weather alert score jumped to 1362 from an expected 579, marking a 2.53x spike and representing a drift status shift from the prior anomaly reading. With 670 active alerts currently exceeding both short-term upper band (1197) and long-term upper band (1151), severe weather conditions are significantly more widespread than typical seasonal patterns, though this elevated state appears to be consolidating rather than continuing to escalate.
NOAA weather alert score jumped to 1414 from expected 603, marking a 3.75 standard deviation spike well above the short-term band (170-1036) and triggering short-term anomaly status while maintaining long-term anomaly flagging at 3.01 sigma. The 696 active alerts indicate genuine severe weather escalation across US regions.

NOAA weighted alert score 1185, within normal range for US weather activity
NOAA alert score 1182, elevated vs expected 509
NOAA weather alert score increased to 1198 from expected 678 (1.31x), signaling elevated severe weather activity with 564 total active alerts; while short-term conditions appear normal within the -118–1474 band, the long-term drift status persists as the score remains above the 96–1140 baseline band, indicating sustained above-average alert levels.
