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 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.

Tropical Storm Bonnie Moves over Eastern North Pacific

Tropical Storm Bonnie moved over the Eastern North Pacific Ocean on Saturday. At 5:00 p.m. EDT on Saturday the center of Tropical Storm Bonnie was located at latitude 11.3°N and longitude 88.0°W which put it about 130 miles (210 km) west-southwest of Managua, Nicaragua. Bonnie was moving toward the west at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 1000 mb.

Tropical Storm Bonnie moved across Central America and over the Eastern North Pacific Ocean on Saturday. The center of Bonnie’s circulation moved along the border between Nicaragua and Costa Rica. Bonnie dropped heavy rain on parts of Nicaragua and Costa Rica. It took about 12 hours for Tropical Storm Bonnie to cross Central America. Bonnie’s circulation was intact when it emerged over the Eastern North Pacific Ocean. The inner end of a rainband wrapped around the center of Tropical Storm Bonnie and an eye was visible on conventional and microwave satellite images. A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 70 miles (110 km) from the center of Bonnie.

Tropical Storm Bonnie will move through an environment favorable for intensification during the next 36 hours. Bonnie will move over water where the Sea Surface Temperatures are near 28˚C. It will move under an upper level ridge over Central America and the Eastern North Pacific Ocean. The upper level winds are weak in the ridge and there will be little vertical wind shear. Tropical Storm Bonnie will intensify during the next 36 hours. Bonnie is likely to strengthen to a hurricane by Sunday night. A period of rapid intensification could occur. Bonnie could intensify to a major hurricane early next week.

Tropical Storm Bonnie will move south of a high pressure system over Mexico. The high pressure system will steer Bonnie toward the west-northwest during the next 36 hours. On its anticipated track Tropical Storm Bonnie will remain south of El Salvador and Guatemala.

Tropical Storm Colin Forms on South Carolina Coast

Tropical Storm Colin formed on the coast of South Carolina on Saturday morning. At 8:00 a.m. EDT on Saturday the center of Tropical Storm Colin was located at latitude 33.6°N and longitude 79.3°W which put it about 25 miles (40 km) west-southwest of Myrtle Beach, South Carolina. Colin was moving toward the northeast at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1012 mb.

A Tropical Storm Warning was in effect for the portion of the coast from South Santee River, South Carolina to Duck, North Carolina.

A small low pressure system dropped heavy rain over the area around Charleston, South Carolina on Friday. An area of winds to tropical storm force was detected off the coast of South Carolina on Saturday morning and the National Hurricane Center designated the system as Tropical Storm Colin. The strongest winds were occurring in bands in the eastern side of Tropical Storm Colin, which was over the Atlantic Ocean. Winds to tropical storm force extended out 70 miles (110 km) in the eastern side of Colin’s circulation. The winds over land were weaker. The heaviest rain was also falling in the bands over the Atlantic Ocean.

Tropical Storm Colin will move through an environment that is unfavorable for intensification during the next 36 hours. Although the Sea Surface Temperatures off the coast of North Carolina are near 27˚C, the center of Colin’s circulation is likely to move along the coast. An upper level trough over the eastern U.S. will produce southwesterly winds that will cause moderate vertical wind shear. Proximity to land and vertical wind shear are likely to prevent Tropical Storm Colin from strengthening during the next 36 hours.

The upper level trough will steer Tropical Storm Colin toward the northeast during the next 36 hours. On its anticipated track, the center of Tropical Storm Colin will move along the coast of North Carolina. Colin could bring gusty winds and locally heavy rain to the coast of North Carolina.

Elsewhere, Tropical Storm Bonnie was moving along the border between Nicaragua and Costa Rica. At 8:00 a.m. EDT on Saturday the center of Tropical Storm Bonnie was located at latitude 11.2°N and longitude 85.8°W which put it about 65 miles (105 km) southeast of Managua, Nicaragua. Bonnie was moving toward the west at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1002 mb. Tropical Storm Bonnie will move over the Eastern North Pacific Ocean in a few hours.

A Tropical Storm Warning was in effect for the portion of the Caribbean coast from Limon, Costa Rica to Sandy Bay Sirpi, Nicaragua. A Tropical Storm Warning was also in effect for the portion of the Pacific coast from Cabo Blanco, Costa Rica to the border between Nicaragua and Honduras.
