Tropical Storm Elida Starts to Weaken

Leave a reply

Tropical Storm Elida started to weaken on Saturday evening as it moved over the Eastern North Pacific Ocean west of Baja California.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Elida was located at latitude 20.6°N and longitude 124.8°W which put the center about 970 miles (1560 km) west of the southern tip of Baja California.  Elida was moving toward the north-northwest at 13 m.p.h. (21 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 993 mb.

Tropical Storm Elida started to weaken on Saturday evening after Elida had strengthened almost to hurricane intensity earlier in the day.  Tropical Storm Elida started to move over cooler Sea Surface Temperatures which is what caused Elida to weaken.  The cooler Sea Surface Temperatures were already starting to affect the structure of Elida’s circulation.  Bands in the northern side of Tropical Storm Elida consisted primarily of showers and lower clouds.  Thunderstorms were still occurring in bands in the southern half of Elida’s circulation.

The distribution of winds speeds around Tropical Storm Elida continued to be asymmetrical.  Winds to tropical storm force extended out 160 miles (260 km) in the eastern side of Elida’s circulation.  Winds to tropical storm force extended out 115 miles (185 km) in the western half of Tropical Storm Elida.

Tropical Storm Elida will move through an environment that will be unfavorable for intensification during the next 24 hours.  Elida will move over water where the Sea Surface Temperatures are near 24°C.  It will move under the southeastern part of an upper level trough that is off the West Coast of the U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Elida’s circulation.  Those winds will cause the vertical wind shear to increase.  The combination of cooler Sea Surface Temperatures and more vertical wind shear will cause Tropical Storm Elida to weaken steadily on Sunday.

Tropical Storm Elida will move around the western part of a high pressure system that is over the Eastern North Pacific Ocean.  The high pressure system will steer Elida toward the north during the next 24 hours.  On its anticipated track, Tropical Storm Elida will remain far to the west of Baja California.

Elsewhere over the Eastern North Pacific Ocean, Tropical Depression Six-E formed south of Baja California.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Depression Six-E was located at latitude 11.3°N and longitude 109.1°W which put the center about 805 miles (1290 km) south of the southern tip of Baja California.  The tropical depression was moving toward the west-northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1008 mb.

Tropical Depression Six-E is forecast to strengthen to a hurricane by early next week.

Tropical Depression Six-E Forms South of Mexico

Tropical Depression Six-E formed over the Eastern North Pacific Ocean south of Mexico early on Sunday.  At 5:00 a.m. EDT on Sunday the center of Tropical Depression Six-E was located at latitude 13.0°N and longitude 99.5°W which put the center about 270 miles (435 km) south of Acapulco, Mexico.  The tropical depression was moving toward the west at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h).  The minimum surface pressure was 1008 mb.

A Tropical Storm Watch is in effect for the portion of the coast from Zihuatanejo to Manzanillo, Mexico.

A low pressure system over the Eastern North Pacific Ocean south of Mexico strengthened early on Sunday and the U.S. National Hurricane Center designated the system as Tropical Depression Six-E.

The circulation around Tropical Depression Six-E exhibited much more organization on Sunday morning.  More thunderstorms developed near the center of the depression’s circulation.  More thunderstorms also formed in bands revolving around the center of Tropical Depression Six-E.  Storms near the center of circulation started to generate upper level divergence that pumped mass away from the tropical depression.  The removal of mass caused the surface pressure to start to decrease.

Tropical Depression Six-E will move through an environment very favorable for intensification during the next 24 hours.  The tropical depression will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over southeastern Mexico and the adjacent part of the Eastern North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Depression Six-E will intensify during the next 24 hours.  It is likely to strengthen to a tropical storm by Monday.  The tropical depression could intensify to a hurricane early next week.

Tropical Depression Six-E will move around the southwestern part of a high pressure system over southern Mexico.  The high pressure system will steer the tropical depression toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Depression Six-E will move a little closer to the coast of southern Mexico.

Bands on the northern side of Tropical Depression Six-E will bring gusty winds and locally heavy rain to parts of the coast of southern Mexico.  Heavy rains could cause flash floods in some locations.

Tropical Depression Six-E Forms West of Mexico

The Eastern North Pacific basin continues to be active tropically.  Tropical Depression Six-E formed west of Mexico on Tuesday.  At 11:00 p.m. EDT on Tuesday the center of Tropical Depression Six-E was located at latitude 12.2°N and longitude 109.9°W which put it about 740 miles (1190 km) south of the southern tip of Baja California.  It was moving toward the west at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1007 mb.

A center of circulation consolidated within a large area of thunderstorms south of Baja California on Tuesday.  A primary band of showers and thunderstorms wrapped around the western and southern sides of the center of circulation.  Additional bands of showers and thunderstorms were beginning to form north and west of the center.  There were not many showers and storms in the eastern half of the circulation.  The thunderstorms near the core of the circulation were beginning generate upper level divergence which was pumping away from depression.

Tropical Depression Six-E will move through an environment that will be favorable for intensification.  It will move over water where the Sea Surface Temperature (SST) is near 29°C.  Tropical Depression Six-E is near the western end of an upper level ridge and the upper level winds are relatively weak.  Warm SSTs and little vertical wind shear should allow the depression to strengthen during the next several days.  Tropical Depression Six-E is likely to become a tropical storm on Wednesday and it could become a hurricane later this week.

Tropical Depression Six-E is moving south of a subtropical ridge which is steering the depression toward the west.  The subtropical ridge is expected to continue to steer the depression toward the west during the next few days.  On its anticipated track the depression is expected to move away from the coast of Mexico.
