Primary Threat: Flooding Rainfall
While Boris is not expected to become a major wind event, the storm’s greatest danger comes from excessive rainfall.

These conditions could trigger life-threatening flash floods and mudslides.

Weather Intelligence Center Analysis
Boris highlights a common early-season Eastern Pacific threat: relatively weak tropical storms that produce significant flooding. Even though wind speeds remain modest, the combination of tropical moisture and rugged terrain can create dangerous flash flooding and landslide conditions across southern Mexico. Meanwhile, nearby Tropical Storm Cristina continues to bring heavy rainfall concerns to parts of Central America.
