Hurricane Rosa intensifies to Category 4 storm in Pacific Ocean

Swells are forecast to affect parts of the coastlines of southwestern Mexico, the southern Baja California Peninsula, and Southern California.</s>MEXICO CITY (AP)  Hurricane John is moving off Mexico”s western coast, having absorbed Tropical Storm Ileana, and is expected to stir up heavy surf and drop rain on the southern portions of the Baja California peninsula while keeping away from landfall.

Another tropical storm was farther out in the Pacific and a subtropical storm formed in the northern Atlantic, though neither posed a threat to land.

The U.S. National Hurricane Center said John had maximum sustained winds of 105 mph (165 kph) late Tuesday but was no longer expected to grow into a major hurricane as it moved northwestward parallel to Baja California before veering off into the Pacific late in the week.</s>Hurricane Rosa intensified into a major storm in the Pacific Ocean, with maximum sustained winds of 145 miles per hour, the National Hurricane Center said late Thursday.

Swells generated by Rosa are forecast to affect parts of the coastlines of southwestern Mexico, the southern Baja California Peninsula, and Southern California later this week and over the weekend.

“These swells are likely to cause life-threatening surf and rip current conditions,” the Miami-based center said.

The Category 4 storm was moving west at around 7 mph at 2 a.m. ET on Friday.

No coastal watches or warnings were in effect, the NHC said.</s>MEXICO CITY (Reuters) - Hurricane Rosa, headed for Baja California, weakened in the Pacific Ocean and was forecast to further wane in the coming days, the U.S. National Hurricane Center (NHC) said on Friday.

It was about 625 miles (1,005 km) southwest of the southern tip of Baja California and moving northwest at almost 6 mph (9 kph). Rosa was expected to reach Baja California on Monday as a tropical storm.

Hurricane-force winds extend outward up to 30 miles from Rosa's center and tropical-storm-force winds extend outward up to 105 miles.

No coastal watches or warnings have been put into effect.

Rosa is forecast to continue moving west Thursday before making a turn northwest on Friday and Saturday.

The hurricane is tracking through the Pacific Ocean close to Mexico and threatening to unleash a barrage of wind and rain. 



Rosa is moving towards the west near 10mph (17km/h) and this motion is expected to continue tonight.



A turn toward the west-northwest is expected on Friday, before then turning towards the northwest on Saturday and then the north on Sunday.

There will be wind speeds of almost 125mph (205km/h) with higher gusts, before the storm strengthens again tonight. 



Fluctuations in strength are possible Friday and Friday night.



Rosa will then weaken on Saturday and Sunday.



Hurricane-force winds will reach out up to 35 miles (55km) from the centre and tropical-storm-force winds will extend up to 115 miles (185km).

The Mexican Navy automated station on Clarion Island has reported sustained winds of 38mph (61km/h) and a wind gust of 53mph (85km/h), according to the National Hurricane Centre.



Rosa will create swells which will affect parts of the coasts of southwestern Mexico.



Other areas affected will include the southern Baja California Peninsula, and southern California late this week and over the weekend. 



The swells are likely to cause life-threatening surf and rip current conditions.

According to NOAA's latest advisory: "Conventional satellite imagery show a large area of cold cloud tops near the center, and there is a hint of an eye in the first-light visible images.



"Microwave imagery indicates that the eye structure underneath the overcast has become better defined, with less evidence of dry air entrainment than seen yesterday." Hurricane Rosa is the tenth hurricane of Pacific hurricane season.



Pacific hurricane season began on May 15 in the eastern Pacific, and on June 1 in the central Pacific. 



Both with end on November 30, after bringing dangerous storm systems across warm waters.</s>The category 4 storm has intensified over the Pacific Ocean and is packing winds of 145mph, according to the National Hurricane Center (NHC). In its 10am update, NHC warned: “Little significant change in strength is forecast today, with gradual weakening anticipated by Saturday, and further weakening at a faster rate expected early next week.” Rosa is expected to turn northwest on Friday before moving north into Saturday and then north-northeast on Sunday. “Life-threatening surf and rip current conditions” are expected to hit southwest Mexico, the southern Baja California Peninsula and southern California by the end of this week.

No coastal warnings or watches are in place but weather forecasters are keeping a close eye on the storm as it churns over the sea at 9mph. National Weather Service (NWS) San Diego warned “large swells are headed our way” despite the storm's expected weakening on Friday into Saturday. Swells could generate waves as high as three metres. Rosa is set to be a tropical storm when it hits Baja California, Mexico, early next week but this could still bring winds of up to 73mph. HURRICANE ROSA PATH MAPPED: WHERE IS HURRICANE ROSA NOW?

High wind gusts of this speed can fell trees and down power lines, as well as cause power outages and property damage. Heavy rainfall could also see widespread flooding, as was the case with Hurricane Florence when it hit the Carolina coast. AccuWeather Senior Meteorologist Dan Pydynowski said: “The track of Rosa will keep it well west of Mexico through the weekend, meaning the primary impact to land through the weekend will be limited to rough surf and rip currents along the western coast of Mexico. “Regardless of its exact intensity as it approaches the Baja, moisture from Rosa will be pulled northward and northeastward across northern Mexico and into the southwestern United States.

“Interaction with a non-tropical weather feature, a southward dip in the jet stream, may allow rain to become widespread and temperatures to plunge over the western US, including much of California.” Rainfall has been sparse up until now with about 0.5 inches falling across the Desert Southwest during October.
