98L over subtropical Atlantic may acquire subtropical characteristics, 97E in eastern Pacific expected to develop

98L over subtropical Atlantic may acquire subtropical characteristics, 97E in eastern Pacific expected to develop

There are currently no active tropical cyclones in the Atlantic or eastern Pacific basins, but there is a low pressure system that may develop in each basin. In the Atlantic, a non-tropical low (Invest 98L) is developing a new center of circulation and could gradually acquire subtropical characteristics by early Thursday. In the eastern Pacific, a well-defined low pressure system (Invest 97E) is likely to develop into a tropical depression over the next day or two as it tracks westward…

Category 4 Hector expected to remain south of Hawaii, John a Category 2, Kristy forms in the eastern Pacific, SS Debby forms in the North Atlantic

Category 4 Hector expected to remain south of Hawaii, John a Category 2, Kristy forms in the eastern Pacific, SS Debby forms in the North Atlantic

The tropics are very active today. In the Central Pacific, Hurricane Hector is currently a Category 4 hurricane, slightly weaker than yesterday when it neared Category 5 intensity. Hector is expected to pass south of the Hawaiian Islands, but a Tropical Storm Watch is currently in effect for Hawaii’s Big Island. In the far eastern Pacific, Hurricane John is gradually strengthening and is now a Category 2 hurricane. To the west of John is newly formed Tropical Storm Kristy, which…

Hector now a major hurricane, TD 11-E gradually strengthening, several invests may develop

Hector now a major hurricane, TD 11-E gradually strengthening, several invests may develop

The eastern Pacific basin is very active with one hurricane (Hector), one tropical depression (11-E), and two systems likely to become tropical depressions over the next couple days (Invests 94E and 95E). There is also one non-tropical low (Invest 97L) over the high-latitude Atlantic which could gradually acquire tropical or subtropical characteristics over the next few days. Hurricane Hector, now a Category 3 hurricane after briefly attaining Category 4 status last night, is expected to slowly weaken as it moves…

Hector now a hurricane, two more areas of interest in the eastern Pacific

Hector now a hurricane, two more areas of interest in the eastern Pacific

Tropical Storm Hector intensified into the fourth hurricane of the 2018 Pacific hurricane season early Thursday. Hector is the first hurricane to form in the east Pacific basin since Fabio in early July. Hector is likely to intensify into a major hurricane as it tracks generally westward over the next several days. It is too soon to determine if Hector will have direct impacts in Hawaii. As of 8:00 a.m. PDT (11:00 a.m. EDT) Thursday, Hurricane Hector was centered near…

Invests 91E, 92E likely to develop soon over the eastern Pacific

Invests 91E, 92E likely to develop soon over the eastern Pacific

Two areas of low pressure over the eastern Pacific basin are becoming better organized today and are close to developing into tropical depressions. The eastern Pacific has not yet seen a new tropical cyclone form this July, which is extremely unusual. This is somewhat surprising for what was anticipated to be a very active or even possibly hyperactive season by experts, since July is normally one of the most active months in the eastern Pacific. Behind 91E and 92E, another…

A line of Pacific disturbances that pose no land threat

A line of Pacific disturbances that pose no land threat

There continues to be no new tropical cyclones active in either the Atlantic or Eastern Pacific basins. However, there are three areas of disturbed weather currently being monitored for development in the Eastern Pacific and one in the Central Pacific. The easternmost disturbance, which has not yet formed, is expected to develop into a low pressure system by early next week. The UKMET and ECMWF models both develop this system into a tropical depression by late Wednesday as it moves…

Two non-threatening, low-chance disturbances in the Pacific

Two non-threatening, low-chance disturbances in the Pacific

Overall, the tropics are quiet today in the Atlantic and eastern Pacific. There are, however, two low-chance disturbances in the eastern and central Pacific, but neither poses any threat to land. The first of the two disturbances, Invest 91C over the central Pacific, has become less organized since yesterday. As of 18:00 UTC Tuesday, Invest 91C was located near 14.2°N 146.9°W, and was moving generally westward. Maximum sustained winds were 25 knots (30 mph), with an estimated minimum pressure of…

Beryl hanging on as a subtropical storm, 99E could develop over the east-central Pacific

Beryl hanging on as a subtropical storm, 99E could develop over the east-central Pacific

Subtropical Storm Beryl is barely hanging on as a subtropical cyclone this morning, with a small area of deep convection to the southeast of the center. However, Beryl should become a remnant low tonight or on Monday morning, since it is about to move away from the Gulf Stream in about 12 hours. Beryl’s remnants may reach Newfoundland on Tuesday, but they are likely to be very weak by that time and minimal impact is anticipated. In the eastern Pacific,…

Beryl’s remnants still may regenerate this weekend

Beryl’s remnants still may regenerate this weekend

The remnants of Hurricane Beryl have become better organized today and still have a low chance to regenerate into a tropical or subtropical cyclone during the next day or two. Environmental conditions are only marginal for development, with wind shear moderate to strong and sea surface temperatures are expected to cool by Sunday. As of 18:00 UTC Friday, the remnants of Beryl were located near 34.0°N 68.4°W, and were moving north-northeastward at about 10 mph. Maximum sustained winds were 25…

Tropical Depression Two forms over the deep tropical Atlantic, Fabio now a tropical storm over the eastern Pacific

Tropical Depression Two forms over the deep tropical Atlantic, Fabio now a tropical storm over the eastern Pacific

The tropical wave over the central tropical Atlantic has acquired a small, closed circulation, and has maintained persistent deep convection for some time now. As a result, the National Hurricane Center (NHC) issued advisories on Tropical Depression Two. The depression may strengthen into Tropical Storm Beryl during the next day or two before encountering strong wind shear as it approaches the Lesser Antilles. In the eastern Pacific, Fabio is quickly weakening and is now a tropical storm. Tropical Depression Two…
