Tropical Storm Boris Special Discussion Number   6
NWS National Hurricane Center Miami FL       EP022026
1200 PM CST Mon Jun 08 2026

An ASCAT overpass revealed that the center of the storm, although 
still somewhat elongated, is located to the south of the previously 
estimated track.  Therefore a special advisory is being issued to 
relocate the center farther offshore of the coast of Guerrero, 
Mexico.  Based on this relocation, the landfall time has been 
delayed.

Also, data from the scatterometer overpass indicated that the 
intensity needs to be adjusted slightly to 40 kt.  Since the system 
remains disorganized, however, little change in strength is 
anticipated before landfall.

The threat of very heavy rainfall continues to be the primary 
hazard of concern, which should result in flash flooding and 
mudslides in mountainous terrain.

This special advisory is being released in lieu of the 1800 UTC 
intermediate advisory.
 
 
Key Messages:
 
1. Heavy rainfall associated with Tropical Storm Boris will impact
portions of southern Mexico. This rainfall may produce
life-threatening flooding and mudslides, especially in areas of
steep terrain.
 
2. Tropical storm conditions are expected to reach the coast of
southern Mexico within the Tropical Storm Warning area tonight or 
early Tuesday.
