00:49 Teddy Becomes a Major Hurricane, Takes Aim on Bermuda Hurricane Teddy continues to move through the Atlantic. It is expected to move close to, if not over, Bermuda.

At a Glance Tropical Storm Adrian is the earliest tropical storm on record to form in the northeastern Pacific Basin.

Southern Mexico or Guatemala could see impacts from this tropical system by early next week. This is a developing weather story. Please click here for the latest updates.

The eastern Pacific is off to a record start in the 2017 hurricane season as Tropical Storm Adrian formed a few hundred miles southwest of El Salvador.

This is the earliest tropical cyclone to form in the northeast Pacific in the satellite era. This record was previously held by Alma in 1990 .

Here's the latest from the National Hurricane Center:

Tropical Storm Adrian formed about 360 miles southwest of San Salvador, El Salvador, and is moving slowly toward the west-northwest.

Adrian is forecast to be near hurricane strength by late Thursday.

No direct impacts are expected in Central America the next few days.

The storm is expected to curl northward and impact the mountains of Guatemala and southern Mexico late this weekend or early next week, potentially as a hurricane.

Tropical Storm Adrian is anticipated to remain just offshore of Central America while traveling parallel to the coast through the end of this week. Late this weekend or early next week, it may curl back toward the coastline of southern Mexico or Guatemala, potentially as a hurricane.

However, there are differences regarding the track and intensity of this system among the computer models, which will make a difference in what, if any, impacts to expect on the coast.

Water temperatures south of El Salvador and Guatemala are in the low to mid-80s, and this system is located in an area with low wind shear, which could foster further development.

(The red-shaded area denotes the potential path of the center of the tropical cyclone. Note that impacts (particularly heavy rain, high surf, coastal flooding) with any tropical cyclone may spread beyond its forecast path.)

Heavy rain may lead to flooding and mudslides in portions of southern Mexico and the mountains of Guatemala early next week. Some areas may see 3 to 5-plus inches of rain as the storm slowly moves inland.

Additionally, high winds and coastal flooding are possible impacts, but the extent depends on the exact strength and movement of this system, which remains uncertain at this time.

The eastern Pacific season begins May 15, which is about a half-month earlier than the Atlantic season. The earlier start date is due to warmer waters and typically weaker wind shear earlier in the season as compared to the Atlantic.
