Tropical Storm Andrea has formed in the Atlantic, marking the first storm of the 2025 Atlantic hurricane season, according to the National Hurricane Center.

Andrea is moving toward the east-northeast for the next day or so, with maximum sustained winds near 40 mph (65 km/h).

Little change in strength is expected today. Weakening is expected to begin tonight, with Andrea dissipating by Wednesday night.

The tropical-storm-force winds extend outward up to 45 miles (75 km) from the center.

Forecasters within NOAA’s National Weather Service predict above-normal hurricane activity in the Atlantic basin this year.

The weather agency’s outlook for the 2025 Atlantic hurricane season, which spans from June 1 to November 30, predicts a 30 percent chance of a near-normal season, a 60 percent chance of an above-normal season, and a 10 percent chance of a below-normal season.

The agency is forecasting a range of 13 to 19 total named storms (winds of 39 mph or higher). Of those, 6-10 are predicted to become hurricanes (winds of 74 mph or higher), including 3-5 major hurricanes (category 3, 4 or 5; with winds of 111 mph or higher). NOAA has a 70 percent confidence in its estimates.
