At a Glance The Eastern Pacific hurricane season has begun a week early.

Tropical Depression One-E formed Thursday afternoon in the open waters of the Eastern Pacific Ocean.

This system will pose no threat to land and is not expected to become a tropical storm.

Tropical Depression One-E formed on Thursday afternoon well off the west coast of Mexico, kicking off the 2018 Eastern Pacific hurricane season, which doesn't officially begin until May 15.

The tropical depression is currently centered more than 1,400 miles west-southwest of the southern tip of Mexico's Baja California.​​​​​​

Additional strengthening is not expected as One-E is approaching an area of stronger wind shear to its west.

Tropical Depression One-E will, therefore, be short-lived, and given it's far from land and has weak steering winds, it will be no threat to land as it drifts toward the west-northwest through Friday night.

Though not expected, if the depression were to become a tropical storm, it would earn the first name of the 2018 Eastern Pacific hurricane season: Aletta.

Another Early Start?

This is a case of déjà vu.

One year ago Wednesday, Tropical Storm Adrian became the earliest tropical cyclone on record to form in the Eastern Pacific Basin.

Adrian became a tropical depression, then strengthened to a tropical storm on May 9, 2017, south of the Pacific coasts of Mexico and Guatemala before wind shear tore it apart the following day.

The Eastern Pacific hurricane season runs from May 15 through Nov. 30, beginning roughly two weeks earlier than the Atlantic hurricane season. According to the National Hurricane Center, an average Eastern Pacific season has its first named storm by the second week of June .

Since 2000, however, 19 named storms have formed in May in the Eastern Pacific Basin. Nine of those storms eventually became hurricanes and six became major hurricanes (Category 3 or stronger ).

And, unlike the current system, some of these storms had land impact.

Five of those May storms made landfall either in southeastern Mexico's Gulf of Tehuantepec or in Central America. One of these, Barbara in 2013, made landfall as a hurricane along the Gulf of Tehuantepec coast.

The 2015 Eastern Pacific hurricane season got off to a record start , including a frenetic May, fueled by an intensifying El Niño.

Hurricane Andres formed over the open waters on May 29, then intensified to Category 4 intensity as the calendar turned to June.

That was followed immediately by another Category 4 hurricane, Blanca , which first became a tropical depression on May 31.

Blanca went on to become the earliest landfalling tropical storm on record in Baja California, moving ashore on June 8.

The monstrous weather front is pushing sustained winds of about 55km/h (33mph) according to the US National Hurricane Centre (NHC) office in Miami, Florida. The NHC warned: “At 2am PDT (9am UTC), the centre of Tropical Depression One-E was located near latitude 12.6 North, longitude 128.6 West. “The depression is moving toward the west near 10 mph.

“A turn toward the northwest with a decrease in forward speed is expected during the next couple of days.” Strong upper winds are expected to cause some weakening over the next 48 hours with hopes the tropical depression will devolve into a remnant low by tonight or early on Saturday. The NHC added: “Despite the depression's deteriorating structure, recent ASCAT data confirmed that the maximum winds remain near 30kt. “Since the shear is forecast to strengthen further, it will become increasingly more difficult for the depression to sustain organised deep convection near its centre, and the system is likely to degenerate into a remnant low by 24 hours.

“The remnant low should then dissipate in about 3 days.” The tropical depression’s presence does not pose any threat to land at the moment, but meteorologists are intently tracking its movement for the first telltale signs of hurricane season. The Eastern Pacific hurricane season is scheduled to officially begin on May 15 and these might be the first rumblings of what is about to come. Hurricane season in the Central Pacific will soon follow in June 2018.

Meanwhile, out in the Atlantic, hurricane season typically kicks off in the summer between June and November, but hurricanes have been known to wreak havoc as early as May.

Last year, Tropical Storm Adrian was the earliest tropical cyclone to develop in the Eastern Pacific Ocean on May 10, reaching within 600km of Mexico. Dominic Davis, a meteorologist for The Weather Channel, warned on Thursday: “This is really a go-nowhere storm which is good news, so we don’t have to worry about it affecting ay land. “So it will start to lose steam by Saturday evening.

“Good reminder though, the Eastern Pacific hurricane season does kick off May 15. “That’s the official start of hurricane season but we know it can happen any time before that like we’re seeing now, so here’s a good time to start brushing up on your hurricane awareness.” Last year’s hurricane season was a particularly devastating time for the US and the Caribbean with a grand total of 17 named storms, 10 hurricanes and 6 major hurricanes – the fifth most active weather season since 1851. Most notably Hurricane Harvey swept through Texas, Hurricane Irma blasted Florida and Hurricane Maria caused unimaginable damaged across the Caribbean.
A tropical depression forms in the Pacific ocean. It is not supposed to threaten land, and is also the first storm of the season.
