The Aqua satellite of NASA went across Hurricane Olivia and discovered belts of thunderstorms draping around its eye and enhanced thunderstorm built-up over the southern quadrant of the tempest. The eastern quadrant also displayed powerful tempests.
Infrared satellite information on September 4 at 5:45 a.m. EDT, from the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument on board the Aqua satellite displayed coldest cloud top temperatures in the southern and eastern southern quadrants in Olivia. In those regions, cloud crowns had temperatures near −70°F (−56.6°C). NASA research has discovered that cloud pinnacle temperatures that could have the potential to cause heavy rainfall.
Also, the infrared information presented forecasters with a view of nearby SSTs (sea surface temperatures). Tropical cyclones need SSTs at least close to 80°F (26.6°C) to preserve force. The National Hurricane Center (NHC) forecasters mentioned at 5 a.m. EDT on September 4 that “Olivia has around 24–36 H or so left over warm SSTs with slightly approving upper wind conditions.”
The NHC, at 5 a.m. EDT, noted the Hurricane Olivia’s center was positioned near longitude 117.2° west and latitude 16.9° north. That is around 1,015 km (630 miles) southwest of the Baja California’s southern tip.
Olivia is traveling toward the west close to 19 kph (12 mph) and the hurricane is predicted to twist west-northwestward with a boost in forward speed on Wednesday. Maximum persistent winds are close to 130 kph (80 mph) with higher breezes. Some strengthening is estimated, and Olivia could turn out a category 2 hurricane tonight, with steady fading beginning early Thursday, September 6.
On the other end, NASA’s JPL in Pasadena, California, will organize a live-streamed Science Conversation at 11 a.m. PDT on September 7, during which professionals will converse regarding the role of the organization’s Dawn spacecraft in looking at the creation of our solar system and the imminent conclusion of its 11-year mission.
