Why This Matters
- A category 2 landfall on the northern US Gulf coast brings the risk of damaging winds, storm surge and heavy rain to densely populated coastal areas.
- Evacuation orders affecting millions mean large-scale disruption and the potential for significant property damage.
- As the first hurricane of a late Atlantic season, it follows an unusually quiet stretch and will test preparedness across the region.
Background
The Atlantic hurricane season typically runs from June through November, with activity usually peaking in late summer or early autumn. A first hurricane arriving this late in the season is unusual, and the Gulf of Mexico is a familiar path for storms that threaten the US coastline, where storm surge is often the deadliest hazard.
Key Perspectives
Forecasters: Projecting landfall as a category 2 hurricane and monitoring where and how hard Isaias will hit.
Residents in coastal communities: Facing evacuation orders and preparing homes, including boarding up windows ahead of the storm.
Emergency authorities: Issuing evacuation orders affecting millions of people across the threatened coastline.
What to Watch
- The exact landfall location and timing along the northern Gulf coast.
- Whether Isaias strengthens or weakens before it comes ashore.
- Post-landfall movement inland and the risk of storm surge and flooding.
