Seymour Becomes a Hurricane

Tropical Depression 20 formed in the Eastern Pacific Ocean on Sunday and by Monday at 11 a.m. It exploded into a new hurricane named Seymour.

NASA created an animation of satellite imagery, which shows the development of the new hurricane.

A tropical depression forms when a low-pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds below 39 mph.

The 20th tropical depression of the Eastern Pacific Ocean hurricane season formed on Sunday, Oct. 23 at 5 a.m. EDT.

National Hurricane Center suggests that Seymour’s cloud pattern continues to increase in organization.

The cyclone’s small central dense overcast has become circular and increasingly symmetric since the last advisory, with plenty of cold-topped deep convection, particularly near the center.

NOAA’s GOES-West satellite captured infrared and visible imagery that showed the rapid intensification of the storm over 30 hours.

NASA’s Goddard Space Flight Center created an animation of data that spans from Oct. 21 to early on Oct. 24.

It shows the development of Tropical Depression 20 and explosive growth into Hurricane Seymour on Oct. 24.

At 11 a.m. EDT (1500 UTC) on Oct. 24 the center of Hurricane Seymour was located near 15.2 degrees north latitude and 109.8 degrees west longitude.

That puts the center of the depression about 450 miles south of Manzanillo, Mexico.

The National Hurricane Center said that Seymour is moving toward the west-northwest near 15 mph, and this motion with some decrease in forward speed is expected during the next couple of days.

Maximum sustained winds have increased to near 75 mph with higher gusts. Additional strengthening is likely, and Seymour is expected to become a major hurricane on Tuesday, Oct. 25.
