On March 20 at EDT (0945 UTC) NASA’s Aqua satellite tv for pc noticed Tropical Cyclone Eliakim in infrared mild. The MODIS instrument confirmed coldest cloud high temperatures and strongest storms (yellow) as chilly as minus 50 levels Fahrenheit (minus 45.5 levels Celsius) have been pushed southeast of the middle.

NASA’s Aqua satellite tv for pc analyzed Tropical Cyclone Eliakim in infrared mild and located hotter cloud high temperatures as wind shear continued to pummel the storm. Wind shear has elongated Eliakim and pushed precipitation south of the storm’s middle.
Infrared mild supplies beneficial cloud high temperature information on tropical cyclones. The larger and colder the cloud tops, the stronger the uplift within the storm and stronger the storms may be. Since March 19, infrared imagery from NASA satellites have proven cloud tops warming in Eliakim. Warmer cloud tops imply the storm has been weakening whereas being battered by sturdy northerly vertical wind shear.
On March 20 at EDT (0945 UTC) the MODIS instrument or Moderate Resolution Imaging Spectroradiometer aboard NASA’s Aqua satellite tv for pc noticed Tropical Cyclone Eliakim in infrared mild. The MODIS information confirmed coldest cloud high temperatures have been as chilly as minus 50 levels Fahrenheit (minus 45.5 levels Celsius) in storms that have been pushed southeast of the middle of circulation. The MODIS picture confirmed the northern facet of the storm was devoid of rainfall.
At 11 a.m. EDT (1500 UTC) on March 20, 2018, the Joint Typhoon Warning Center (JTWC) issued the ultimate bulletin on Tropical Cyclone Eliakim. At that point, Eliakim was situated roughly 499 nautical miles south of St. Denis, La Reunion Island. It was centered close to 29.four levels south latitude and 54.1 levels east longitude. Eliakim was shifting to the south-southeast at 15 mph (13 knots/24 kph). Maximum sustained winds have been nonetheless close to 52 mph (45 knots/74 kph).
Eliakim was shifting south-southeast. JTWC forecasters famous “Eliakim has begun rapid extra-tropical transition and is expected to become a strong gale-force cold core low with an expansive wind field [later in the day on March 20].”
