Tropical Storm Cristobal - June 2-10, 2020
Tropical Storm Amanda formed off the coast of Guatemala on May 31st and
made landfall a short while later in Central
America. The low pressure area associated with Amanda moved north
into the Yucatan Peninsula on June 1st, and
gained enough organization to be classified as Tropical Depression Three
that afternoon in the eastern Bay of Campeche.
The cyclone strengthened into Tropical Storm Cristobal on the 2nd while
making a slow cyclonic loop back toward the
Yucatan Peninsula. Making landfall on the 3rd, the system regained
tropical depression status while weakening.
After entering northwest Guatemala, Cristobal turned to the north.
Just before moving back into the Gulf of
Mexico on the 5th, it regained tropical storm strength. Thunderstorms
were displaced northeast of the center
due to the upper level trough steering it northward. Cristobal made
landfall in Louisiana on the 7th, then
moved through the Mississippi Valley while becoming a non-tropical low.
Cristobal moved across Lake Superior on
the 10th before entering Ontario.
