Narda Weakens to a Tropical Storm

Former Hurricane Narda weakened to a tropical storm as it moved over cooler water west of Baja California on Saturday evening.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Narda was located at latitude 18.7°N and longitude 125.9°W which put the center about 1070 miles (1725 km) west-southwest of the southern tip of Baja California.  Narda was moving toward the north-northwest at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 991 mb.

Former Hurricane Narda weakened to a tropical storm as it moved over cooler water west of Baja California.  Many of the thunderstorms in Narda’s circulation weakened when it moved over the cooler water.  There were still some thunderstorms occurring near the center of Tropical Storm Narda.  However, those storms generated much less upper level divergence.  As a result, the inflow of mass in the lower levels of the atmosphere was greater than the outflow of mass in the upper levels.  The greater inflow of mass caused the surface pressure to increase.

Winds to tropical storm force extended out 125 miles (200 km) from the center of Tropical Storm Narda.

Tropical Storm Narda will move through an environment that will be unfavorable for intensification during the next 24 hours.  Narda will move over water where the Sea Surface Temperatures are near 24°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Narda will weaken during the next 24 hours as it moves over colder Sea Surface Temperatures.

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

 

Hurricane Narda Spins Southwest of Baja California

Hurricane Narda was spinning southwest of Baja California on Friday morning.  At 5:00 a.m. EDT on Friday the center of Hurricane Narda was located at latitude 16.4°N and longitude 120.7°W which put the center about 835 miles (1340 km) west-southwest of the southern tip of Baja California.  Narda was moving toward the west at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 980 mb.

Hurricane Narda did not change much during the past 36 hours.  Thunderstorms were still occurring near the center of Narda’s circulation.  Bands of showers and thunderstorms were revolving around the center of Hurricane Narda.  Storms near the center of Narda generated upper level divergence that pumped mass away from the hurricane.  The outflow of mass in the upper levels was nearly equal to the inflow of mass in the lower levels of the atmosphere.  So, the surface pressure did not change much.

The size of the circulation around Hurricane Narda did increase during the past 36 hours.  Winds to hurricane force extended out 45 miles (75 km) from the center of Narda’s circulation.  Winds to tropical storm force extended out 185 miles (295 km) from the center of Hurricane Narda.

Hurricane Narda will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Narda will move over water where the Sea Surface Temperatures are near 27°C.  An upper level ridge that is over northwestern Mexico and the Eastern North Pacific will produce easterly winds that will blow toward the top of Narda’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will still inhibit intensification, but the wind shear may not be enough to stop intensification. Hurricane Narda could intensify during the next 24 hours.

Hurricane Narda will move around the southern side of a high pressure system that is over Mexico and the Eastern North Pacific Ocean.  The high pressure system will steer Narda toward the west during the next 24 hours.  On its anticipated track, Hurricane Narda will move farther away from Baja California.  Narda is forecast to move toward the north during the weekend when it reaches the western end of the high pressure system.

Hurricane Narda Moves South of Baja California

Hurricane Narda moved south of Baja California on Wednesday.  At 5:00 p.m. EDT on Wednesday the center of Hurricane Narda was located at latitude 15.1°N and longitude 112.3°W which put the center about 560 miles (905 km) south-southwest of the southern tip of Baja California.  Narda was moving toward the west at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 976 mb.

The distribution of thunderstorms in Hurricane Narda became more asymmetrical on Wednesday.  Most of the thunderstorms were occurring in bands in the western side of Narda’s circulation.  Bands in the eastern side of Hurricane Narda consisted primarily of showers and lower clouds.  Storms near the center of Narda still generated upper level divergence that pumped mass away to the west of the hurricane.

An upper level ridge over northwestern Mexico was producing easterly winds that blew toward the top of Hurricane Narda.  Those winds caused moderate vertical wind shear.  The moderate vertical wind shear caused the distribution of thunderstorms to become asymmetrical.

The size of the circulation around Hurricane Narda increased on Wednesday.  Winds to hurricane force extended out 30 miles (50 km) from the center of Narda’s circulation.  Winds to tropical storm force extended out 140 miles (225 km) from the center of Hurricane Narda.

Hurricane Narda will move through an environment that will become more favorable for intensification during the next 24 hours.  Narda will move over water where the Sea Surface Temperatures are near 28°C.  The upper level ridge that is over northwestern Mexico will continue to produce easterly winds that will blow toward the top of Narda’s circulation.  However, those winds are forecast to weaken on Thursday, which would mean there will be less vertical wind shear.  The vertical wind shear will still inhibit intensification, but the wind shear may not be enough to stop intensification.  Hurricane Narda could intensify during the next 24 hours if the upper level winds weaken.

Hurricane Narda will move around the southern side of a high pressure system that is over Mexico and the Eastern North Pacific Ocean.  The high pressure system will steer Narda toward the west during the next 24 hours.  On its anticipated track, Hurricane Narda will move southwest of Baja California.

Narda Intensifies to a Hurricane

Former Tropical Storm Narda intensified to a hurricane over the Eastern North Pacific Ocean southwest of Mexico on Tuesday.  At 11:00 a.m. EDT on Tuesday the center of Hurricane Narda was located at latitude 15.8°N and longitude 107.3°W which put the center about 295 miles (475 km) southwest of Manzanillo, Mexico.  Narda was moving toward the west at 13 m.p.h. (21 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 981 mb.

Former Tropical Storm Narda intensified to a hurricane on Tuesday.  The inner end of a rainband wrapped around the western side of Narda’s circulation.  Bands of showers and thunderstorms were revolving around the center of Hurricane Narda.  Storms near the center of Narda generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

The strongest winds were blowing in the northern side of Hurricane Narda.  Winds to hurricane force extended out 20 miles (30 km) in the northern half of Narda’s circulation.  Winds to tropical storm force extended out 70 miles (110 km) from the center of Hurricane Narda.

Hurricane Narda will move through an environment that will be favorable for intensification during the next 24 hours.  Narda 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 that is over northwestern Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Narda’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear will not be enough to stop intensification.  Hurricane Narda will intensify during the next 24 hours.

Hurricane Narda will move around the southern side of a high pressure system that is over Mexico and the Eastern North Pacific Ocean.  The high pressure system will steer Narda toward the west during the next 24 hours.  On its anticipated track, Hurricane Narda will move south of Baja California on Wednesday.

Tropical Storm Narda Forms South of Mexico

Tropical Storm Narda formed over the Eastern North Pacific Ocean south of Mexico on Sunday.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Narda was located at latitude 15.3°N and longitude 100.5°W which put the center about 180 miles (290 km) south-southeast of Zihuatanejo, Mexico.  Narda was moving toward the northwest at 10 m.p.h. (16 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.

A low pressure system over the Eastern North Pacific Ocean south of Mexico strengthened on Sunday and the U.S. National Hurricane Center designated the system as Tropical Storm Narda.

The circulation around Tropical Storm Narda was slowly becoming more organized.  Some thunderstorms began to develop near the center of Narda’s circulation.  Bands of showers and thunderstorms were starting to revolve around the center of Tropical Storm Narda.

The strongest winds were in the northern half of Tropical Storm Narda.  Winds to tropical storm force extended out 70 miles (110 km) in the northern side of Narda’s circulation.  The winds in the southern side of Tropical Storm Narda were blowing at less than tropical storm force.

Tropical Storm Narda will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Narda 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 that is over northern Mexico.  The upper level ridge will produce northeasterly winds that will blow toward the top of Narda’s circulation.  Those winds will cause moderate vertical wind shear.  The moderate vertical wind shear will inhibit intensification, but the wind shear may not be enough to stop intensification.  Tropical Storm Narda could intensify on Monday if the vertical wind shear does not increase.

Tropical Storm Narda will move around the southern side of a high pressure system that is over Mexico and the Eastern North Pacific Ocean.  The high pressure system will steer Narda toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Narda will remain west of the coast of Mexico.

Tropical Storm Mario Weakens

Tropical Storm Mario weakened on Monday night as it moved over the Eastern North Pacific Ocean west of Baja California.  At 5:00 a.m. EDT on Tuesday the center of Tropical Storm Mario was located at latitude 21.9°N and longitude 115.7°W which put the center about 375 miles (605 km) west of the southern tip of Baja California.  Mario was moving toward the northwest at 12 m.p.h. (19 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.

Tropical Storm Mario weakened on Monday night as it moved over cooler water west of Baja California.  Many of the thunderstorms in Tropical Storm Mario dissipated when Mario moved over the cooler water.  A few thunderstorms were still occurring near the center of Mario’s circulation.  Most of the bands revolving around the center of Tropical Storm Mario consisted primarily of showers and lower clouds.  Since the storms near the center of Mario were not generating much upper level divergence, the surface pressure was increasing.

The circulation around Tropical Storm Mario was still small.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Mario’s circulation.

Tropical Storm Mario will move through an environment that will be unfavorable for intensification during the next 24 hours.  Mario 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 near the west coast of the U.S.  The upper level trough will produce southerly winds that will blow toward the top of Mario’s circulation.  Those winds will cause moderate vertical wind shear.  The combination of moderate vertical wind shear and cooler Sea Surface Temperatures will cause Tropical Storm Mario to continue to weaken during the next 24 hours.

Tropical Storm Mario will move around the around the southwestern part of a high pressure system over the southwest U.S. and northwest Mexico.  The high pressure system will steer Mario toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Mario will move west of Baja California.

Tropical Storm Mario Strengthens

Tropical Storm Mario strengthened during Sunday night as it moved over the Eastern North Pacific Ocean south of Baja California.  At 5:00 a.m. EDT on Monday the center of Tropical Storm Mario was located at latitude 19.4°N and longitude 112.3°W which put the center about 285 miles (460 km) south-southwest of the southern tip of Baja California.  Mario was moving toward the west-northwest at 12 m.p.h. (19 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 995 mb.

Tropical Storm Mario strengthened during Sunday night.  The distribution of thunderstorms in Mario became more symmetrical.  Thunderstorms continued to develop near the center of Mario’s circulation.  Thunderstorms were also occurring in bands revolving around the center of Tropical Storm Mario.  Storms near the center of Mario generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

Even though Tropical Storm Mario strengthened, the size of Mario’s circulation remained small.  Winds to tropical storm force extended out 35 miles (55 km) from the center of Tropical Storm Mario.

Tropical Storm Mario will move through an environment that will become unfavorable for intensification during the next 24 hours.  Mario will move over water where the Sea Surface Temperatures are near 26°C.  It will move under the southeastern part of an upper level trough  that is near the west coast of the U.S.  The upper level trough will produce southwesterly winds that will blow toward the top of Mario’s circulation.  Those winds will cause the vertical wind shear to increase.  The combination of more vertical wind shear and cooler Sea Surface Temperatures will cause Tropical Storm Mario to start to weaken during the next 24 hours.

Tropical Storm Mario will move around the around the southern part of a high pressure system over the southwest U.S. and northwest Mexico.  The high pressure system will steer Mario toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Mario will remain southwest of Baja California.

Tropical Storm Mario Re-develops South of Baja California

Tropical Storm Mario re-developed over the Eastern North Pacific Ocean south of Baja California on Sunday morning.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Mario was located at latitude 18.5°N and longitude 110.2°W which put the center about 305 miles (490 km) south of the southern tip of Baja California.  Mario was moving toward the west-northwest at 8 m.p.h. (13 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.

After almost dissipating during Friday night, Tropical Storm Mario re-developed south of Baja California on Sunday morning.  A distinct low level center of circulation re-formed on Sunday morning.  More thunderstorms started to develop near the low level center of circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Mario.  Storms near the center of Mario began to generate upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Mario was still small.  Wind to tropical storm force extended out 25 miles (40 km) in the northeastern quadrant of Mario’s circulation.  The winds in the other parts of Tropical Storm Mario were blowing at less than tropical storm force.

Tropical Storm Mario will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Mario will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southeastern part of upper level ridge over the southwest U.S. and northwest Mexico.  The upper level ridge will produce northeasterly winds that will blow toward the top of Mario’s circulation.  Those winds will cause moderate vertical wind shear.  The moderate vertical wind shear will inhibit intensification, but the wind shear will not be enough to prevent intensification.  Tropical Storm Mario is likely to intensify during the next 24 hours.

Tropical Storm Mario will move around the around the southern part of a high pressure system over the southwest U.S. and northwest Mexico.  The high pressure system will steer Mario toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Mario will southwest of Baja California.

 

Tropical Storm Mario Forms Near Zihuatanejo

Tropical Storm Mario formed over the Eastern North Pacific Ocean near Zihuatanejo, Mexico on Friday morning.  The government of Mexico issued a Tropical Storm Watch for a portion of the coast.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Mario was located at latitude 17.2°N and longitude 101.9°W which put the center about 40 miles (65 km) south-southwest of Zihuatanejo, Mexico.  Mario was moving toward the west-northwest 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 1006 mb.

A Tropical Storm Watch is in effect for the portion of the coast from Lazaro Cardenas to Punta San Telmo, Mexico.

A low pressure system over the Eastern North Pacific Ocean near Zijuatanejo strengthened on Friday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Mario.

The circulation around Tropical Storm Mario exhibited more organization on Friday morning.  More thunderstorms developed near the center of Mario’s circulation.  Thunderstorms were also occurring in short bands that were revolving around the center of Tropical Storm Mario.  Storms near the center of Mario generated upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Mario was very small.  Winds to tropical storm force extended out 25 miles (40 km) in the northwestern quadrant of Mario’s circulation.  The winds in the other parts of Tropical Storm Mario were blowing at less than tropical storm force.

Tropical Storm Mario will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Mario will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southern part of upper level ridge over Mexico.  The upper level ridge will produce northeasterly winds that will blow toward the top of Mario’s circulation.  Those winds will cause moderate vertical wind shear.  The circulation around Tropical Storm Mario could also pull drier air over Mexico in the tropical storm.  The moderate vertical wind shear and drier air will inhibit intensification.  Tropical Storm Mario could intensify during the next 24 hours if the center remains over the ocean.

Tropical Storm Mario will move around the around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer Mario toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Mario will move near the coast of Michoacan.

Tropical Storm Mario will bring gusty winds and locally heavy rain to coastal parts of Michoacan.  Heavy rain could cause flash floods in some locations.

Hurricane Lorena Moves Toward Baja California

Hurricane Lorena was moving toward Baja California on Wednesday evening.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Lorena was located at latitude 23.4°N and longitude 113.2°W which put the center about 110 miles (175 km) south-southwest of Cabo San Lazaro, Mexico.  Lorena was moving toward the northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 981 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Santa Fe to Punta Eugenia, Mexico.

A Tropical Storm Watch is in effect for the portion of the coast from Todos Santos to Sante Fe, Mexico.  A Tropical Storm Watch is in effect for the portion of the coast from Santa Rosalia to Bahia de Los Angeles, Mexico.

Hurricane Lorena strengthened a little more on Wednesday.  The inner end of a rainband wrapped around the center of Lorena’s circulation.  However, an eye was not visible on satellite images.  Bands of showers and thunderstorms were revolving around the center of Hurricane Lorena.  Storms near the center of Lorena generated upper level divergence that pumped mass away to the northeast of the hurricane.

The circulation around Hurricane Lorena was small.  Winds to hurricane force extended out 20 miles (30 km) in the northeastern quadrant of Lorena’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Hurricane Lorena.

Hurricane Lorena will move through an environment that will become unfavorable for intensification during the next 24 hours.  Lorena will move over water where the Sea Surface Temperatures are near 25°C.  It will move under the southeastern part of an upper level trough that is west of Baja California.  The upper level trough will produce southwesterly winds that will blow toward the top of Lorena’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 Hurricane Lorena to weaken on Thursday.

Hurricane Lorena will move around the western end of a high pressure system that is over Mexico.  The high pressure system will steer Lorena toward the north during the next 24 hours.  The upper level trough that is west of Baja California will steer Lorena toward the northeast later on Thursday.  On its anticipated track, Hurricane Lorena will approach the coast of Baja California between Cabo San Lazaro and Punta Eugenia on Friday.

Hurricane Lorena will weaken to a tropical storm before it reaches the coast of Baja California.  Lorena will bring strong winds and locally heavy rain to parts of Baja California.  Heavy rain could cause flash floods in some locations.

Elsewhere, Hurricane Kiko strengthened to a Category 4 hurricane on the Saffir-Simpson Scale far to the east-southeast of Hawaii.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Kiko was located at latitude 13.8°N and longitude 132.3°W which put the center about 1560 miles (2510 km) east-southeast of Hilo Hawaii.  Kiko was moving toward the west at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 145 m.p.h. (235 km/h) and there were wind gusts to 170 m.p.h. (275 km/h).  The minimum surface pressure was 944 mb.
