Tropical Storm Vicente made landfall and weakened quickly to a tropical depression on Oct. 23. NOAA’s GOES-West satellite captured a visible image of the fading, and now post-tropical storm raining on southwestern Mexico.
On Oct. 23 at 2 p.m. EDT (1800 UTC), NOAA’s GOES-West satellite provided a visible image of Vicente. The storm appeared almost shapeless, but there was a larger concentration of thunderstorms near its circulation center. Vicente degenerated into a remnant low while moving inland over the Mexican state of Michoacan.
At 11 a.m. EDT (1500 UTC), the center of Post-Tropical Cyclone Vicente was located near latitude 18.4 degrees north, longitude 102.4 degrees west. The post-tropical cyclone is moving toward the north-northwest near 12 mph (19 kph) and this general motion is expected to continue today, bringing the system farther inland over Mexico. Maximum sustained winds have decreased to near 30 mph (45 kph) with higher gusts. The system is expected to dissipate later today. The estimated minimum central pressure is 1008 millibars.
Despite weakening, the NHC cautioned that Vicente’s remnants are expected to produce 3 to 6 inches of rain with local amounts to 10 inches through today, Oct. 23, over portions of Guerrero, Michoacan, Colima, and Jalisco in Mexico. This rainfall could produce life-threatening flash flooding and landslides within mountainous terrain.
Oct. 22, 2018 – NASA Sees Tiny Tropical Storm Vicente Near Southwestern Mexico’s Coast
NASA-NOAA’s Suomi NPP satellite passed over the Eastern Pacific Ocean and captured a visible image of the small tropical storm named Vicente.
Vicente developed on Friday, Oct. 19 as Tropical Depression Twenty-Three-E (TD 23E). TD23E formed about 85 miles (135 km) west-southwest of Puerto San Jose Guatemala and moved west-northwest while intensifying. Later in the day TD23E strengthened into a tropical storm and was renamed Vicente, but the storm was moving slowly. Because of the slow movement, heavy rains fell over portions of El Salvador, Guatemala and southeastern Mexico. Vicente then moved west
On. Oct. 21, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA’s Suomi NPP satellite passed over Vicente and captured a visible image of the storm. VIIRS showed that the storm was small in diameter. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center. Vicente appeared less organized in the image than it did hours earlier.
On Oct. 22 at 11 a.m. EDT (1500 UTC) NOAA’s National Hurricane Center (NHC) in Miami, Fla. noted that the center of Tropical Storm Vicente was located near latitude 14.9 degrees north and longitude 100.8 degrees west. Vicente is moving toward the west-northwest near 12 mph (19 kph) and a turn to the northwest is expected today followed by a turn to the north-northwest on Tuesday, Oct. 23. Maximum sustained winds are near 45 mph (75 kph) with higher gusts. Weakening is forecast, and Vicente is expected to become a tropical depression by tonight or Tuesday.
On Oct. 22 although there are no coastal watches or warnings in effect, the NHC cautioned that interests along the southern and southwestern coasts of Mexico should monitor the progress of Vicente. On the forecast track, the center of Vicente is expected to approach the southwestern coast of Mexico on Tuesday, Oct. 23. The cyclone’s circulation is expected to dissipate near the southwestern coast of Mexico by Wednesday, Oct. 24.
