NASA sees Ramon degenerate to a trough

October 05, 2017

A trough is an elongated area of low pressure and that's exactly what former Tropical Storm Ramon has become in the eastern Pacific Ocean, along the southwestern coast of Mexico. NASA-NOAA's Suomi NPP satellite provided a look at the temperatures of Ramon's cloud tops and showed some strong thunderstorms remained in the stretched out remnants.

Infrared imagery on Oct. 5 at 4:12 a.m. EDT (0812 UTC) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite showed bursts of strong convection northwest of what was Ramon's center of circulation and is now part of an elongated area low pressure. Those thunderstorms had cloud top temperatures colder than minus degrees 70 Celsius (minus 94 degrees Fahrenheit).

At 5 a.m. EDT (0900 UTC) on Thursday, October 5, 2017 the National Hurricane Center (NHC) noted that "the shower activity near the center of circulation NHC was tracking has practically vanished. Since strong wind shear will prevail in this area, regeneration is not anticipated."

At that time, the remnants of Ramon were located near 15.0 degrees north latitude and 102.5 degrees west longitude. That's about 215 miles (350 km) southwest of Acapulco, Mexico. The remnants of Ramon were moving toward the west-northwest near 12 mph (19 kph). Maximum sustained winds were near 25 mph (35 kph) and weakening. The estimated minimum central pressure was 1008 millibars.

The remnants are expected to dissipate later on Oct. 5.

Dispatch 6: Strange Times
Covid has disrupted the most basic routines of our days and nights. But in the middle of a conversation about how to fight the virus, we find a place impervious to the stalled plans and frenetic demands of the outside world. It's a very different kind of front line, where urgent work means moving slow, and time is marked out in tiny pre-planned steps. Then, on a walk through the woods, we consider how the tempo of our lives affects our minds and discover how the beats of biology shape our bodies.
