Genevieve Rapidly Intensifies to a Major Hurricane

Hurricane Genevieve rapidly intensified to a major hurricane over the Eastern North Pacific Ocean southwest of Mexico on Sunday morning.  At 11:00 a.m. EDT on Sunday the center of Hurricane Genevieve was located at latitude 13.4°N and longitude 109.4°W which put the center about 515 miles (825 km) southwest of Manzanillo, Mexico.  Genevieve was moving toward the west-northwest at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (220 km/h).  The minimum surface pressure was 963 mb.

A circular eye with a diameter of 20 miles (32 km) formed at the center of Hurricane Genevieve.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Genevieve’s circulation.  Storms near the core of Genevieve generated strong upper level divergence that pumped large amounts of mass away from the hurricane.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

Winds to hurricane force extended out 45 miles (75 km) in the northern side of Hurricane Genevieve.  Winds to hurricane force extended out 15 miles (25 km) in the southern side of Genevieve’s circulation.  Winds to tropical storm force extended out 195 miles (315 km) from the center of Hurricane Genevieve.

Hurricane Genevieve will move through an environment favorable for intensification during the next 24 hours.  Genevieve will move over water where the Sea Surface Temperatures are near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Genevieve will intensify during the next 24 hours.  Genevieve could continue to intensify rapidly during the next few hours.   Hurricane Genevieve could strengthen to a Category 5 hurricane on the Saffir-Simpson Scale.

Hurricane Genevieve will move around the southwestern part of a high pressure system that is over the Southwest U.S.  The high pressure system will steer Genevieve toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Genevieve will move parallel to the west coast of Mexico.

Elsewhere, Hurricane Fausto was weakening slowly as it moved over the Central North Pacific Ocean.  At 11:00 a.m. EDT on Sunday the center of Hurricane Fausto was located at latitude 19.9°N and longitude 141.1°W which put the center about 910 miles (1465 km) east of Hilo, Hawaii.  Fausto was moving toward the west at 14 m.p.h. (24 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 977 mb.

Genevieve Strengthens to a Hurricane

Former Tropical Storm Genevieve strengthened to a hurricane over the Eastern North Pacific Ocean southwest of Mexico on Saturday.  At 11:00 p.m. EDT on Saturday the center of Hurricane Genevieve was located at latitude 12.1°N and longitude 106.7°W which put the center about 500 miles (810 km) south-southwest of Manzanillo, Mexico.  Genevieve was moving toward the west-northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (150 km/h).  The minimum surface pressure was 987 mb.

Former Tropical Storm Genevieve strengthened to a hurricane on Saturday.  The inner end of a rainband wrapped around the eastern and northern sides of the center of Genevieve’s circulation.  An eye appeared to be forming at the center of Hurricane Genevieve.  Bands of showers and thunderstorms were revolving around the center of Genevieve’s circulation.  Storms near the center of Genevieve 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 occurring in the section of the rainband that wrapped around the northeastern part of the center of Hurricane Genevieve.  Winds to hurricane force extended out 20 miles in the northeastern quadrant of Genevieve’s circulation.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Hurricane Genevieve.

Hurricane Genevieve will move through an environment favorable for intensification during the next 24 hours.  Genevieve will move over water where the Sea Surface Temperatures are near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Genevieve will intensify during the next 24 hours.  Genevieve could intensify rapidly at times.  Genevieve is likely to strengthen to a major hurricane by early next week.

Hurricane Genevieve will move around the southwestern part of a high pressure system that is over the Southwest U.S.  The high pressure system will steer Genevieve toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Genevieve will move parallel to the west coast of Mexico.

Elsewhere, Hurricane Fausto was nearing the Central Pacific Ocean.  At 11:00 p.m. EDT on Saturday the center of Hurricane Fausto was located at latitude 19.5°N and longitude 138.8°W which put the center about 1060 miles (1702 km) east of Hilo, Hawaii.  Fausto was moving toward the west at 13 m.p.h. (21 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 971 mb.

 

Hurricane Fausto Strengthens a Little More

Hurricane Fausto strengthened a little more on Friday morning as it moved toward the Central Pacific Ocean.  At 11:00 a.m. EDT on Friday the center of Hurricane Fausto was located at latitude 18.6°N and longitude 131.2°W which put the center about 1560 miles (2510 km) east of Hilo, Hawaii.  Fausto was moving toward the west at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h).  The minimum surface pressure was 967 mb.

Hurricane Fausto continued to strengthen early on Friday.  A circular eye with a diameter of 17 miles (28 km) was at the center of Fausto’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Fausto’ circulation.  Storms near the center of Fausto generated more upper level divergence that pumped more mass away from the hurricane.  The removal of more mass caused the surface pressure to decrease.

The distribution of wind speeds around Hurricane Fausto became more symmetrical on Friday.  Winds to hurricane force extended out 45 miles (75 km) from the center of Fausto’s circulation.  Winds to tropical storm force extended out 185 miles (295 km) from the center of Hurricane Fausto.

Hurricane Fausto will move into an environment that will become unfavorable for intensification during the next 24 hours.  Fausto will move over water where the Sea Surface Temperatures are near 26°C.  It will move under the middle of an upper level ridge that is southwest of Mexico.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  There is drier air just to the north and west of Hurricane Fausto.  The drier air is likely to inhibit the development of new thunderstorms in bands in the northern and western parts of Fausto’s circulation.  Hurricane Fausto is likely to weaken during the next 24 hours because of the effects of the drier air.

Hurricane Fausto will move around the southern part of a high pressure system that is over the Eastern North Pacific Ocean.  The high pressure system will steer Fausto toward the west during the next 24 hours.  On its anticipated track, Hurricane Fausto will continue to move toward the Central Pacific Ocean.  Fausto could be near the Hawaiian Islands by the middle of next week.

Elsewhere over the Eastern North Pacific Ocean, Tropical Depression Seven-E formed south of Mexico.  At 11:00 a.m. EDT on Friday the center of Tropical Depression Seven-E was located at latitude 9.0°N and longitude 100.5°W which put the center about 605 miles (975 km) south of Zihuatanejo, Mexico.  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 1005 mb.

Fausto Strengthens to a Hurricane

Former Tropical Storm Fausto strengthened to a hurricane on Monday evening as it moved over the Eastern North Pacific Ocean southwest of Baja California.  At 11:00 p.m. EDT on Monday the center of Hurricane Fausto was located at latitude 14.7°N and longitude 117.3°W which put the center about 745 miles (1200 km) southwest of the southern tip of Baja California.  Fausto was moving toward the northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 988 mb.

Former Tropical Storm Fausto strengthened to a hurricane on Monday evening.  The inner end of a rainband wrapped around the center of Fausto’s circulation.  A small eye appeared to be forming at the center of Hurricane Fausto.  Bands of showers and thunderstorms were revolving around the center of Fausto’s circulation.  Storms near the center of Fausto generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the northeastern part of Hurricane Fausto.  Winds to hurricane force extended out 25 miles (40 km) in the northeastern quadrant of Fausto’s circulation.  Winds to tropical storm force extended out 195 miles (315 km) in the southern half of Hurricane Fausto.  Winds to tropical storm force extended out 90 miles (145 km) in the northern half of Fausto’s circulation.

Hurricane Fausto will move through an environment that will be favorable for intensification during the next 24 hours.  Fausto will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge that is southwest of Mexico. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Hurricane Fausto will intensify during the next 24 hours.  Fausto could strengthen to a major hurricane on Wednesday.

Hurricane Fausto will move around the southwestern part of a high pressure system that is over the Eastern North Pacific Ocean.  The high pressure system will steer Fausto toward the west-northwest during the next 24 hours.  On its anticipated track, Hurricane Fausto will continue to move farther away from Mexico.

Tropical Storm Fausto Develops South of Baja California

Tropical Storm Fausto developed over the Eastern North Pacific Ocean south of Baja California on Sunday afternoon.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Fausto was located at latitude 12.4°N and longitude 112.7°W which put the center about 750 miles (1205 km) south-southwest of the southern tip of Baja California.  Fausto was moving toward the west-northwest at 13 m.p.h. (21 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.

Former Tropical Depression Six-E strengthened on Sunday afternoon and the U.S. National Hurricane Center designated the system as Tropical Storm Fausto.

Tropical Storm Fausto was strengthening gradually on Sunday afternoon.  More thunderstorms formed near the center of Fausto’s circulation.  Thunderstorms were also occurring in bands in the western side of Tropical Storm Fausto.  Bands in the eastern side of Fausto’s circulation still consisted primarily of showers and lower clouds.  Storms near the center of Fausto began to generate upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the northwestern part of Tropical Storm Fausto.  Winds to tropical storm force extended out 80 miles (130 km) in the northwestern quadrant of Fausto’s circulation.  The winds in the other parts of Tropical Storm Fausto were blowing at less than tropical storm force.

Tropical Storm Fausto will move through and environment that will be favorable for intensification during the next 24 hours.  Fausto will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge that is southwest of Mexico.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Storm Fausto will intensify during the next 24 hours.  Fausto is likely to strengthen to a hurricane on Monday.

Tropical Storm Fausto will move around the southwestern part of a high pressure system that is over the Eastern North Pacific Ocean.  The high pressure system will steer Fausto toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Fausto will move farther away from Mexico.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Elida was weakening slowly as it churned west of Baja California.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Elida was located at latitude 23.2°N and longitude 125.9°W which put the center about 1015 miles (1635 km) west of the southern tip of Baja California.  Elida was moving toward the north-northwest at 10 m.p.h. (16 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 996 mb.

Tropical Storm Elida Starts to Weaken

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 Storm Elida Churns Northwest

Tropical Cyclone Elida churned toward the northwest over the Eastern North Pacific Ocean west of Baja California on Friday.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Elida was located at latitude 17.1°N and longitude 121.9°E which put the center about 875 miles (1410 km) west-southwest of the southern tip of Baja California.  Elida was moving toward the west-northwest at 12 m.p.h. (19 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 994 mb.

Tropical Cyclone Elida maintained its intensity on Friday.  The inner end of a rainband wrapped around the western side of the center of Elida’s circulation.  However, the circulation around Elida appeared to pull some drier air into the eastern side of the tropical storm.  Thunderstorms in some of the bands in the eastern side of Tropical Storm Elida weakened.  Bands of showers and thunderstorms were still revolving around the center of Elida’s circulation.  Storms near the center of Elida also still generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass in the upper levels was nearly equal to the convergence of mass in the lower levels of the atmosphere.  So, the surface pressure did not change much on Friday.

The distribution of wind speeds around Tropical Storm Elida was still asymmetrical on Friday.  Winds to tropical storm force extended out 195 miles (315 km) in the eastern side of Elida’s circulation.  Winds to tropical storm force only extended out 105 miles (165 km) in the western side of Tropical Storm Elida.

Tropical Storm Elida will move through an environment that will be favorable for intensification for about another 24 hours.  Elida will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the middle of an upper level ridge that is over 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 Storm Elida could still intensify to a hurricane during the next 24 hours.  Elida is likely to start to weaken on Sunday when it moves over cooler water.

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

Tropical Storm Elida Spins Southwest of Baja California

Tropical Storm Elida was spinning over the Eastern North Pacific Ocean southwest of Baja California on Thursday.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Elida was located at latitude 15.7°N and longitude 117.4°E which put the center about 695 miles (1120 km) southwest of the southern tip of Baja California.  Elida was moving toward the west at 10 m.p.h. (16 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 995 mb.

Tropical Storm Elida intensified gradually on Friday as it spun west of Baja California.  Bands of showers and thunderstorms revolved around the center of Elida’s circulation.  Storms near the center of Elida generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The strongest winds were blowing in the eastern side of Tropical Storm Elida.  Winds to tropical storm force extended out 125 miles (200 km) in the eastern half of Elida’s circulation.  The winds in the western half of Tropical Storm Elida were blowing at less than tropical storm force.

Tropical Storm Elida will move through an environment that will be favorable for intensification during the next 24 hours.  Elida will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the middle of an upper level ridge that is over 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 Storm Elida will intensify during the next 24 hours.  Elida is likely to strengthen to a hurricane on Friday.

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

Tropical Storm Elida Develops South of Baja California

Tropical Storm Elida developed over the Eastern North Pacific Ocean South of Baja California on Tuesday night.  At 5:00 a.m. EDT on Wednesday the center of Tropical Storm Elida was located at latitude 14.9°N and longitude 111.8°E which put the center about 565 miles (910 km) south-southwest of the southern tip of Baja California.  Elida was moving toward the west at 15 m.p.h. (24 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.

A low pressure system over the Eastern North Pacific Ocean strengthened on Tuesday night and the U.S. National Hurricane Center designated the system as Tropical Storm Elida.

Numerous thunderstorms formed near the center of Tropical Storm Elida early on Wednesday.  Thunderstorms were also developing in bands revolving around the center of Elida’s circulation.  Storms near the center of Elida generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the northern side of Tropical Storm Elida.  Winds to tropical storm force extended out 60 miles (95 km) in the northern half of Elida’s circulation.  The winds in the southern half of Tropical Storm Elida were blowing at less than tropical storm force.

Tropical Storm Elida will move through an environment that will be very favorable for intensification during the next 24 hours.  Elida will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge that is over 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 Storm Elida will intensify during the next 24 hours.  Elida could intensify rapidly.

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

Tropical Storm Cristina Meanders West of Nicaragua

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.
