Basin and naming guide

NHC Hurricane Basins and Storm Names

The National Hurricane Center tracks tropical cyclones in the Atlantic and Eastern North Pacific, while the Central Pacific Hurricane Center handles the Central North Pacific. Each basin uses its own naming sequence and seasonal context. A storm name is assigned after a system reaches tropical-storm strength; a name appearing on a list does not mean that storm exists.

Start Here, Then Move Toward a Local Decision

Step 1

Identify the Basin

Use the storm identifier, position, and official advisory source to distinguish Atlantic, Eastern Pacific, and Central Pacific systems.

Open all-basin tracker

Step 2

Check the Official Forecast Center

NHC issues Atlantic and Eastern Pacific advisories; CPHC handles Central Pacific systems within its area of responsibility.

Step 3

Separate a Name List From an Active Storm

Names are prepared in advance and used in sequence. Confirm the current advisory before treating a listed name as an active cyclone.

Check season status

Atlantic basin

Atlantic, Caribbean, and Gulf Systems

The Atlantic basin includes the North Atlantic Ocean, Caribbean Sea, and Gulf. Atlantic advisories use the basin's name list and can affect the Americas, Caribbean, Atlantic shipping, and nearby islands.

  • North Atlantic Ocean
  • Caribbean Sea
  • Gulf
  • NHC official advisories

Pacific basins

Eastern and Central Pacific Systems

Eastern Pacific and Central Pacific systems use separate name lists and forecast responsibilities. A cyclone can cross a basin boundary, so the responsible forecast center and advisory source may change while the storm remains the same system.

  • Eastern North Pacific advisories from NHC
  • Central North Pacific advisories from CPHC
  • Separate naming sequences
  • All-basin status belongs on the live tracker

Naming

A Name Does Not Show Strength or Risk

Names make communication easier after tropical-storm strength is reached. They do not describe category, forecast confidence, size, surge, rainfall, or whether a location is threatened.

  • Check classification and advisory time
  • Use the forecast path and hazard products
  • Verify local alerts separately
  • Retired names are replaced after especially destructive storms

Hurricane FAQ

Which hurricane basins does the NHC track?

NHC issues forecasts for the Atlantic and Eastern North Pacific. The Central Pacific Hurricane Center handles the Central North Pacific within its area of responsibility.

Do Atlantic and Pacific hurricanes use the same name list?

No. Atlantic, Eastern Pacific, and Central Pacific systems use separate naming sequences.

When does a tropical system receive a name?

A tropical cyclone receives a name when it reaches tropical-storm strength in its basin. A name on a seasonal list does not mean a storm has formed.

Can a hurricane keep its name after crossing basins?

A cyclone can retain its identity when crossing a basin boundary, while forecast responsibility and advisory products may change. Check the latest official advisory source.

What is HurricaneHub's direct answer for people in the risk zone?

Check your official local warning first, compare it with the current NHC storm position, then decide whether your home, route, or medical needs require earlier action than the county deadline.

How often should hurricane data refresh?

NHC advisories usually update on a cycle set by the storm situation, while NWS alerts can change at any time. HurricaneHub caches public feeds for short windows to reduce latency without hiding official updates.

Is this a replacement for emergency management orders?

No. HurricaneHub summarizes official data for decision support, but evacuation orders, shelter rules, road closures, and rescue instructions come from local emergency management and the National Weather Service.
