Tropical Storm Cristina Meanders West of Nicaragua

Leave a reply

Tropical Storm Cristina was meandering over the Eastern North Pacific Ocean just to the west of northwestern Nicaragua on Tuesday afternoon.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Cristina was located at latitude 12.7°N and longitude 87.8°W which put the center about 110 miles (175 km) west-northwest of Managua, Nicaragua.   Cristina was moving toward the west-northwest at 1 m.p.h. (2 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 Warning is in effect for the portion of the coast from Puerto Sandino, Nicaragua to the border with Honduras.  A Tropical Storm Warning is in effect for the Pacific coast of Honduras.  A Tropical Storm Warning is in effect for the entire coast of El Salvador.

The circulation around Tropical Storm Cristina exhibited more organization on Tuesday afternoon.  More thunderstorms formed near the center of Cristina’s circulation.  New thunderstorms also developed in bands in the western and southern parts of Tropical Storm Cristina.  Bands in the eastern and northern sections of Cristina’s circulation still consisted primarily of showers and lower clouds.  Storms near the center of Cristina generated upper level divergence that pumped mass away to the west of the tropical storm.  The removal of mass in the upper levels of the atmosphere was nearly equal to the convergence of mass in the lower levels.  So, the surface pressure did not change much.

The distribution of wind speeds in Tropical Storm Cristina was asymmetrical.  Winds to tropical storm force extended out 80 miles (130 km) in the southern half of Cristina’s circulation.  The winds in the northern half of Tropical Storm Cristina were blowing at less than tropical storm force.

Tropical Storm Cristina will move through an environment somewhat favorable for intensification during the next 24 hours.  Cristina will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the western side of an upper level low that is over the Southwestern Caribbean Sea.  The upper level low will produce northeasterly winds that will blow toward the top of Cristina’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 prevent intensification.  The vertical wind shear is forecast to be a little less on Wednesday.  Tropical Storm Cristina could intensify slowly during the next 24 hours.

Tropical Storm Cristina will move around the western part of a high pressure system that is over the Northwestern Caribbean Sea.  The high pressure system will steer Cristina toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Cristina will approach the coast of El Salvador on Wednesday evening.

Tropical Storm Cristina will bring strong winds and locally heavy rain to the coast of northwestern Nicaragua, the Pacific coast of Honduras, and the coast of El Salvador.  Heavy rain is likely to cause flash floods in some locations.

Elsewhere, Tropical Depression Boris continued to weaken as it move inland over southern Mexico.  At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Boris was located at latitude 16.9°N and longitude 98.9°W which put the center about 65 miles (105 km) east of Acapulco, Mexico.  Boris was moving toward the northwest at 7 m.p.h. (11 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 1004 mb.

Tropical Storm Boris dropped heavy rain over parts of southern Mexico on early on Tuesday.  Boris weakened to a tropical depression as it moved inland over southern Mexico.  At 8:00 a.m. EDT on Tuesday the center of Tropical Depression Boris was located at latitude 16.7°N and longitude 98.5°W which put the center about 95 miles (150 km) east of Acapulco, Mexico.  Boris was moving toward the northwest at 6 m.p.h. (10 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 1003 mb.

Tropical Depression Boris was dropping heavy rain on parts of southern Mexico early on Tuesday.  The center of Boris’ circulation made landfall on the coast of southern Mexico just to the east of Punta Maldonado.  Boris was dropping heavy rain on parts of Guerrero and Oaxaca.

Tropical Depression Boris will move around the southwestern side of a high pressure system that is over southeastern Mexico.  The high pressure system will steer Boris toward the northwest during the next 24 hours.  On its anticipated track, Tropical Depression Boris will continue to move inland over southern Mexico.

Tropical Depression Boris will continue to drop heavy rain on parts of Guerrero and Oaxaca as it moves farther inland.  Heavy rain is very likely to cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Cristina was meandering near the coast of northwestern Nicaragua.  At 8:00 a.m. EDT on Tuesday the center of Tropical Storm Cristina was located at latitude 12.7°N and longitude 87.8°W which put the center about 110 miles (175 km) west-northwest of Managua, Nicaragua.   Cristina was moving toward the northwest at 3 m.p.h. (5 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 west of Nicaragua strengthened on Monday afternoon and the U.S. National Hurricane Center designated the system as Tropical Storm Cristina.

The distribution of thunderstorms in Tropical Storm Cristina was asymmetrical because of vertical wind shear.  Thunderstorms were occurring in bands in the southern half of Cristina’s circulation.  Bands in the northern half of Tropical Storm Cristina consisted primarily of showers and lower clouds.  Storms near the center of Cristina generated upper level divergence that pumped mass away to the south and west of the tropical storm.  The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Storm Cristina was relatively small.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Cristina’s circulation.

Tropical Storm Cristina will move through an environment somewhat favorable for intensification during the next 24 hours.  Cristina will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the western side of an upper level low that is over the Southwestern Caribbean Sea.  The upper level low will produce northerly winds that will blow toward the top of Cristina’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 prevent intensification.  Tropical Storm Cristina could intensify slowly during the next 24 hours.

Tropical Storm Cristina will move around the western part of a high pressure system that is over the Northwestern Caribbean Sea.  The high pressure system will steer Cristina toward the north-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Cristina will move toward the coast of Honduras and El Salvador.

Tropical Storm Cristina will bring strong winds and locally heavy rain the coast of northwestern Nicaragua, the Pacific coast of Honduras, and the coast of El Salvador.  Heavy rain is likely to cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Boris strengthened a little south of Mexico.  At 2:00 p.m. EDT on Monday the center of Tropical Storm Boris was located at latitude 15.3°N and longitude 99.2°W which put the center about 120 miles (195 km) south-southeast of Acapulco, Mexico.   Boris was moving toward the east-northeast at 3 m.p.h. (5 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.

A Tropical Storm Warning is in effect for the portion of the coast from Laguna de Chacahua to Tecpan de Galeana, Mexico.  The Tropical Storm Warning includes Acapulco.

Tropical Storm Boris will bring strong winds and very heavy rain to parts of Guerrero and Oaxaca.  Heavy rain is likely to cause flash floods in some locations.

(22 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 1005 mb.

Former Tropical Storm Raymond weakened to a tropical depression south of Baja California on Saturday.  Most of the thunderstorms in Raymond’s circulation dissipated.  The bands revolving around the center of Tropical Depression Raymond consisted primarily of showers and lower clouds.  There were no thunderstorms near the center of Raymond’s circulation to generate upper level divergence.  Converging winds in the lower levels of the atmosphere caused the surface pressure to increase.

Tropical Depression Raymond will move through an environment that will be unfavorable for intensification during the next 24 hours.  Raymond will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southwestern part of an upper level ridge that is over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Raymond’s circulation.  Those winds will cause strong vertical wind shear.  The strong wind shear will cause Tropical Depression Raymond to continue to weaken.

Tropical Depression Raymond will move around the western side of a high pressure system that is over Mexico.  The high pressure system will steer Raymond toward the north during the next 24 hours.  On its anticipated track, Tropical Depression Raymond will move across the southern part of Baja California on Saturday night.

Tropical Depression Raymond will bring gusty winds and isolated heavy rain to parts of southern Baja California.

Tropical Storm Raymond Moves West of Mexico

Tropical Storm Raymond moved west of Mexico on Friday afternoon.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Raymond was located at latitude 19.1°N and longitude 106.5°W which put the center about 145 miles (230 km) west of Manzanillo, Mexico.  Raymond was moving toward the northwest at 17 m.p.h. (28 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.

A Tropical Storm Warning was in effect for the portion of the coast from Manzanillo to Cabo Corrientes, Mexico.  A Tropical Storm Warning was in effect for Las Islas Marias.  A Tropical Storm Warning was in effect for the portion of the coast from Los Barriles to Santa Fe, Mexico.

The distribution of thunderstorms in Tropical Storm Raymond was still asymmetrical on Friday afternoon. Thunderstorms were occurring in bands in the southern and western parts of Raymond’s circulation.  Bands in the northern and eastern parts of Tropical Storm Raymond consisted primarily of shower and lower clouds.  Storms near the center of Raymond generated some upper level divergence that pumped mass away to the west of the tropical storm.

The circulation around Tropical Storm Raymond was small.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Raymond’s circulation.

Tropical Storm Raymond will move through an environment that will be only marginally favorable for intensification during the next 24 hours.  Raymond will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southwestern part of an upper level ridge that is over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Raymond’s circulation.  Those winds will cause strong vertical wind shear.  The strong wind shear will inhibit intensification. Tropical Storm Raymond is likely to weaken on Saturday because of the strong vertical wind shear.

Tropical Storm Raymond will move around the western side of a high pressure system that is over Mexico.  The high pressure system will steer Raymond toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Raymond will reach the southern end of Baja California on Saturday.

Tropical Storm Raymond will bring gust winds and locally heavy rain to the southern part of Baja California.  Heavy rain could cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, former Tropical Storm Priscilla weakened west of Baja California.  At 5:00 p.m. EDT on Friday the center of Tropical Depression Priscilla was located at latitude 26.3°N and longitude 115.4°W which put the center about 220 miles (355 km) west-northwest of Cabo San Lazaro, Mexico.  Priscilla was moving toward the north at 6 m.p.h. (10 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 1004 mb.

Tropical Storm Raymond formed over the Eastern North Pacific Ocean south of Mexico on Thursday.  At 2:00 p.m. EDT on Thursday the center of Tropical Storm Raymond was located at latitude 16.1°N and longitude 101.0°W which put the center about 115 miles (185 km) south-southeast of Zihuatanejo, Mexico.  Raymond was moving toward the northwest at 9 m.p.h. (15 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 1002 mb.

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

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

The distribution of thunderstorms in Tropical Storm Raymond was asymmetrical.  Thunderstorms were occurring in bands in the southern and western parts of Raymond’s circulation.  Bands in the northern and eastern parts of Tropical Storm Raymond consisted primarily of shower and lower clouds.  Storms near the center of Raymond started to generate upper level divergence that pumped mass away to the west of the tropical storm.

Tropical Storm Raymond will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Raymond will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge that is over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Raymond’s circulation.  Those winds will cause strong vertical wind shear.  The strong wind shear will inhibit intensification.  Tropical Storm Raymond could intensify a little on Friday if the upper level winds do not get any stronger.

Tropical Storm Raymond will move around the western side of a high pressure system that is over Mexico.  The high pressure system will steer Raymond toward the northwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Raymond will move near the coast of Mexico between Zihuatanejo and Cabo Corrientes on Friday.

Tropical Storm Raymond will bring gusty winds and locally heavy rain to coastal sections of Colima, Michoacan, and western Guerrero.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Priscilla continued to weaken west of Baja California.  At 11:00 a.m. EDT on Thursday the center of Tropical Storm Priscilla was located at latitude 23.8°N and longitude 114.7°W which put the center about 165 miles (265 km) west-southwest of Cabo San Lazaro, Mexico.  Priscilla was moving toward the north-northwest at 8 m.p.h. (13 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 996 mb.

Priscilla Weakens to a Tropical Storm

Former Hurricane Priscilla weakened to a tropical storm over the Eastern North Pacific Ocean south of Baja California on Wednesday afternoon.  At 2:00 p.m. EDT on Wednesday the center of Tropical Storm Priscilla was located at latitude 21.7°N and longitude 112.7°W which put the center about 195 miles (310 km) west-southwest of the southern tip of Baja California.  Priscilla was moving toward the northwest at 7 m.p.h. (11 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 985 mb.

A Tropical Storm Watch was in effect for the portion of the coast from Cabo San Lucas to Cabo San Lazaro, Mexico.

Former Hurricane Priscilla rapidly weakened to a tropical storm south of Baja California on Wednesday.  Thunderstorms around the center of Priscilla’s circulation and in the northern half of the circulation weakened.  Bands in those parts of Tropical Storm Priscilla consisted primarily of showers and lower clouds.  Thunderstorms were still occurring in bands in the southern and western periphery of Priscilla’s circulation.  Weakening of the thunderstorms near the core of Tropical Storm Priscilla greatly reduced the upper level divergence.  With much less upper level divergence the inflow of mass in the lower levels of the atmosphere caused the surface pressure to increase.

The circulation around Tropical Storm Priscilla was still large.  Winds to tropical storm force extended out 160 miles (260 km) from the center of Priscilla’s circulation.

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

Tropical Storm Priscilla will move around the western end of a high pressure system over Mexico.  The high pressure system will steer Priscilla toward the north-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Priscilla will move west of Cabo San Lazaro on Thursday.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Octave continued to gradually weaken far to the southwest of Baja California.  At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Octave was located at latitude 15.4°N and longitude 116.2.°W which put the center about 660 miles (1065 km) southwest of the southern tip of Baja California.  Octave was moving toward the east 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 1003 mb.
