What happened
NOAA/NWS and ECMWF issue the severe-weather alerts that matter for markets: Gulf hurricanes threaten offshore output and refining, heat and cold extremes drive power demand, and droughts or freezes hit crop belts (US corn, Brazil coffee and sugar).
Why it matters
Weather is a supply-and-demand shock to physical commodities on a days-to-weeks horizon — it lifts natural-gas and power demand, curbs energy supply during storms, threatens crop yields, and drives catastrophe losses that hit reinsurers. The signal is the alert and the forecast track, not a price prediction.
Exposed assets
| Ticker | Direction | Rationale |
|---|---|---|
| NG | ▲ | heat and cold extremes spike power-generation demand |
| CORN | ▲ | drought or freeze threatens yields |
| USO | ▲ | Gulf hurricanes curb offshore and refining output |
| RNR | ▼ | reinsurers absorb catastrophe losses |
