Tropical Storm Emilia Absorbs Fabio

The circulation around Tropical Storm Emilia absorbed the circulation of former Tropical Storm Fabio on Wednesday afternoon.

At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Emilia was located at latitude 19.1°N and longitude 117.7°W which put the center about 565 miles (910 km) west-southwest of the southern tip of Baja California.  Emilia was moving toward the northwest at 18 m.p.h. (30 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 990 mb.

At 5:00 p.m. EDT on Wednesday the center of former Tropical Storm Fabio was located at latitude 18.4°N and longitude 120.2°W which put the center about 735 miles (1180 km) west-southwest of the southern tip of Baja California.  Fabio was moving toward the southwest at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1004 mb.

The larger circulation around Tropical Storm Emilia absorbed the smaller circulation around Tropical Storm Fabio on Wednesday.

The absorption of Fabio’s circulation did disrupt the circulation around Tropical Storm Emilia, especially on the western side of its circulation.  Bands in the northern and western parts of Tropical Storm Emilia consisted primarily of showers and lower clouds.  Thunderstorms were still occurring in bands in the southern and eastern parts of Emilia’s circulation.  The interactions of the two circulations also inhibited upper level divergence to the north and west of Tropical Storm Emilia.

Winds to tropical storm force extended out 115 miles (185 km) from the center of Tropical Storm Emilia.

Tropical Storm Emilia will move into an environment that will become unfavorable for intensification during the next 24 hours.  Emilia will move move over water where the Sea Surface Temperatures are near 25°C.  It will move under the axis of an upper level ridge over the Eastern North Pacific Ocean.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Tropical Storm Emilia will weaken when it moves over cooler water on Thursday.

Tropical Storm Emilia will move around the southern part of a subtropical high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Emilia toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Emilia will move farther away from Baja California.

Tropical Storms Emilia and Fabio Interact

The circulations around Tropical Storms Emilia and Fabio were interacting on Tuesday afternoon.

At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Emilia was located at latitude 14.4°N and longitude 115.3°W which put the center about 685 miles (1110 km) south-southwest of the southern tip of Baja California.  Emilia was moving toward the northwest at 3 m.p.h. (5 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 992 mb.

At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Fabio was located at latitude 19.2°N and longitude 113.9°W which put the center about 625 miles (1010 km) west of Manzanillo, Mexico.  Fabio was moving toward the west-northwest at 21 m.p.h. (33 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 997 mb.

The circulations around Tropical Storm Emilia and Fabio were interacting on Tuesday afternoon.  Winds blowing around the southern side of Fabio’s circulation were interacting with winds that were blowing around the northern side of Tropical Storm Emilia.  The interactions were occurring in both the upper and lower troposphere.  The interactions were affecting the structures of both tropical storms.

Tropical Storm Emilia appeared to be the larger and more powerful of the two tropical storms.  Even so, the flow around the southern side of Fabio was having an effect on Emilia’s structure.  Most of the thunderstorms in Tropical Storm Emilia were occurring in bands in the southern half of Emilia’s circulation.  Bands in the northern side of Emilia consisted primarily of showers and low clouds.  Outflow from Tropical Storm Fabio was inhibiting upper level divergence to the north of Tropical Storm Emilia.

The interactions between the two tropical storms was also affecting the distribution of wind speeds in Tropical Storm Emilia.  Winds to tropical storm force extended out 140 miles (220 km) in the southern half of Emilia’s circulation.  Winds to tropical storm force only extended out 70 miles (110 km) in the northern side of Emilia.

The interaction with Tropical Storm Emilia appeared to be contributing to the start of a weakening trend in Tropical Storm Fabio.  The interaction with Emilia was also affecting the structure of Tropical Storm Fabio.  Most of the thunderstorms were occurring in bands in the eastern side of Fabio’s circulation.  Bands in the western part of Tropical Storm Fabio consisted primarily of showers and lower clouds.  Outflow from Tropical Storm Emilia was inhibiting upper level divergence to the south and west of Tropical Storm Fabio,

The interactions between the two tropical storms was also affecting the distribution of wind speeds in Tropical Storm Fabio.  Winds to tropical storm force extended out 100 miles (160 km) in the eastern side of Fabio’s circulation.  Winds to tropical storm force only extended out 35 miles (55 km) in the eastern half of Fabio.

It is possible that the larger circulation around Tropical Storm Emilia could absorb the smaller circulation of Tropical Storm Fabio.  The circulation around Fabio will continue to disrupt part of the circulation in the northern part of Tropical Storm Emilia.  Emilia may not intensify much during the interactions between the two storms.

Tropical Storm Emilia will move through an environment that is otherwise favorable for intensification during the next 24 hours.  Emilia will move move over water where the Sea Surface Temperatures are near 28°C.   It will move under an axis of an upper level ridge over the Eastern North Pacific Ocean.  The upper level winds are weak near the axis of the ridge.  There will be little vertical wind shear except for the shear caused by the outflow from Tropical Storm Fabio.  Tropical Storm Emilia is likely to intensify during the next 24 hours.  Emilia could strengthen to a hurricane.

Tropical Storm Emilia will move around the southern side of a high pressure system over the Eastern North Pacific Ocean.  The interaction with Tropical Storm Fabio is likely to pull Emilia toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Emilia will move farther away from Baja California.  Emilia is likely to be steered toward the west-northwest by the high pressure system after it absorbs Tropical Storm Fabio.

Tropical Storm Fabio Forms Southwest of Mexico

Tropical Storm Fabio formed over the Eastern North Pacific Ocean southwest of Mexico on Monday morning.  At 11:00 a.m. EDT on Monday the center of Tropical Storm Fabio was located at latitude 14.8°N and longitude 106.9°W which put the center about 335 miles (540 km) southwest of Manzanillo, Mexico.  Fabio was moving toward the northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1006 mb.

A low pressure system over the Eastern North Pacific Ocean southwest of Mexico strengthened on Monday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Fabio.  More thunderstorms formed near the center of Fabio’s circulation.  However, the distribution of thunderstorms around Tropical Storm Fabio was asymmetrical.  Thunderstorms were occurring in bands in the southern and western parts of Fabio’s circulation.  Bands in the northern and eastern parts of Tropical Storm Fabio consisted primarily of showers and lower clouds.  Storms near the center of Fabio generated upper level divergence that pumped mass away to the west of the tropical storm.

Winds to tropical storm force extended out 70 miles in the southeastern quadrant of Tropical Storm Fabio.  The winds in the other parts of Fabio’s circulation were blowing at less than tropical storm force.

Tropical Storm Fabio will move through an environment somewhat favorable for intensification during the next 24 hours.  Fabio will move over water where the Sea Surface Temperatures are near 28°C.   It will move under the southern part of an upper level ridge over the Eastern North Pacific Ocean.  The ridge will produce easterly winds that will blow toward the top of Fabio’s circulation.  Those winds will cause some vertical wind shear, but the shear may not be enough to prevent intensification. The circulation around Fabio could interact with the circulation around Tropical Storm Emilia.  Tropical Storm Fabio could intensify during the next 24 hours.

Tropical Storm Fabio is currently being steered by the circulation around Tropical Storm Emilia.  Fabio is forecast to be steered toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Fabio will move farther away from Mexico.  There is a chance that the circulations around Fabio and Tropical Storm Emilia could merge into a single circulation.

Elsewhere, Tropical Storms Carlotta, Daniel and Emilia were spinning over the Eastern North Pacific Ocean.

At 11:00 a.m. EDT on Monday the center of Tropical Storm Carlotta was located at latitude 20.4°N and longitude 127.2°W which put the center about 1125 miles (1805 km) west of the southern tip of Baja California.  Carlotta was moving toward the west at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 1001 mb.

At 11:00 a.m. EDT on Monday the center of Tropical Storm Daniel was located at latitude 15.6°N and longitude 127.7°W which put the center about 1265 miles (2035 km) west-southwest of the southern tip of Baja California.  Daniel was moving toward the northeast at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1005 mb.

At 11:00 a.m. EDT on Monday the center of Tropical Storm Emilia was located at latitude 14.5°N and longitude 114.1°W which put the center about 640 miles (1035 km) west-southwest of the southern tip of Baja California.  Emilia was moving toward the south-southwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (120 km/h).  The minimum surface pressure was 1001 mb.

 

 

Tropical Storm Fabio Develops West of Mexico

Tropical Storm Fabio developed west of Mexico on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Fabio was located at latitude 12.0°N and longitude 107.4°W which put it about 770 miles (1240 km) south-southeast of the southern tip of Baja California.  Fabio was moving toward the west-northwest at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 1000 mb.

The circulation of Tropical Storm Fabio was still organizing.  There was a broad low level center of circulation, but it did not have a well developed inner core.  Multiple bands of showers and thunderstorms were revolving around the broad low level center.  The storms in the rainbands were generating some upper level divergence which was starting to pump mass away from the tropical storm.

Tropical Storm Fabio will move through an environment that is very favorable for intensification.  Fabio will move over water where the Sea Surface Temperature is near 28.5°C.  An upper level ridge northeast of Tropical Storm Fabio will produce easterly winds which will blow toward the top of the circulation.  However, the wind speed will be similar at all levels and there will not be much vertical wind shear.  Tropical Storm Fabio will continue to intensify in the favorable environment.  Once a primary rainband wraps around the center of circulation, an inner core will develop.  Tropical Storm Fabio could intensify rapidly when an eye starts to form.  Fabio could strengthen into a major hurricane in two or three days.

Tropical Storm Fabio was moving south of a subtropical ridge which was steering the tropical storm toward the west-northwest.  A general west-northwesterly motion is expected to continue during the next few days.  On its anticipated track the center of Tropical Storm Fabio will pass well to the south of Baja California.

Elsewhere over the Eastern North Pacific Ocean Tropical Depression Emilia continued to weaken over cooler water.  At 11:00 a.m. EDT on Sunday the center of Tropical Depression Emilia was located at latitude 19.3°N and longitude 123.0°W which put it about 880 miles (1415 km) west-southwest of the southern tip of Baja California.  Emilia was moving toward the west-northwest 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 1006 mb.
