Cyclone phase evolution: Analyses & Forecasts

This page presents historical, analyzed (current), and model-forecast cyclone phase diagrams for northwestern hemisphere cyclones
with the goals of improved structural forecasting, structural transition (subtropical/tropical/extratropical), cyclogenesis, and providing measures of structural predictability.

Please note that these products are experimental and not official forecasts. For official forecasts in the U.S., please refer to the National Weather Service and National Hurricane Center.

To the right are the most recently picked interesting diagrams.
In this case, the UKMET analysis of extratropical transition of Ignacio and "landfall" near the Alaskan border as a weakening extratropical storm.
