NASA Spots Tropical Storm Marty with RapidScat Instrument
With the help of RapidScat, an instrument that monitors ocean winds and helps in providing weather predictions, NASA has a view of the tropical-storm force winds within Tropical Storm Marty.
The Eastern Pacific's seventeenth tropical depression initiated around 5 p.m. EDT on September 26, escalating into Tropical Storm Marty by 11 p.m. that day, a press release states.
By 9 a.m. EDT on September 27, NASA's RapidScat instrument showed that the strongest fluctuating winds were north and east of the center near 35 meters per second, with weaker winds surrounding the rest of the storm and the tropical storm force winds extending outward up to 90 miles from the center.
The National Hurricane Center reported on Monday September 28, that there is a tropical Storm Watch in effect for Acapulco, Mexico to Lazaro Cardenas, Mexico. Around 8 a.m. the NOAA's GOES-West satellite took an infrared image of Tropical Storm Marty engulfing Mexico's west coast.
The center of Tropical Strom Marty was located about 145 miles southwest of Zihuatanejo, Mexico. Marty was moving north about 2 mph, and in a slow motion toward the northeast and is anticipated to near the southwestern coast of Mexico through Tuesday, but will remain offshore.
Winds will remain at 70 mph with higher gusts of wind. A miniature change in strength is expected today, the weakening forecast is expected by tonight or Tuesday. The expected minimum central pressure is 990 millibars.
Marty is expected to bring excess rain, leaving concerns for flooding and mudslides and producing up to 6 to 12 inches of rainfall through Thursday, with isolated amounts close to 20 inches from Sierra Madre del Sur Mountains toward the coast, according to the National Hurricane Center. Then, on Tuesday, September 29, Marty is forecast to turn to the west-northwest and away from the coast.
