Tropical Storm Marie: steady weakening forecast

Observed position, motion and intensity

At 0900 UTC on 7 September 2026, the center of Tropical Storm Marie was near 24.4N 123.7W. In the same observation, Marie was moving northwest at about 8 mph, equivalent to 13 km/h. Maximum sustained winds were near 65 mph, or 100 km/h, while the estimated minimum central pressure was 986 mb. These figures describe the cyclone's observed state at the stated time and are separate from the developments forecast for later. [s2]

Distances from the coast and wind extent

At that time, Marie's center was about 580 mi, or 935 km, west-southwest of Punta Eugenia, Mexico. It was also approximately 700 mi, or 1125 km, southwest of San Diego, California. Tropical-storm-force winds extended outward as far as 115 miles, equivalent to 185 km, from the center. The first two measurements locate the storm relative to two separate places, while the final figure describes the greatest reported outward reach of winds at tropical-storm strength. [s2]

Forecast track and weakening

In its forecast, the National Hurricane Center called for a slight turn toward the west-northwest soon. By Tuesday, Marie was expected to resume a northwestward heading while moving forward faster. Steady weakening was anticipated during the following several days, and the system was forecast to become a post-tropical remnant low Tuesday night or early Wednesday. The turn, increase in forward speed, weakening and post-tropical transition were forecast elements rather than conditions already observed at 0900 UTC. [s2]

Swells and coastal hazards

For roughly the next two days, swells generated by Marie were expected to keep affecting portions of the coast of the Baja California Peninsula and southern California. The National Hurricane Center said those swells were likely to cause life-threatening breaking-wave conditions and life-threatening rip-current conditions. The likelihood applied to both hazards, not only to the breaking waves. This coastal forecast concerned portions of the two shorelines, while the separate steady-weakening forecast applied to the cyclone itself. [s2]
