Tropical Depression Calvin Discussion Number 7
NWS National Hurricane Center Miami FL EP032017
400 AM CDT Tue Jun 13 2017
The cloud pattern associated with Calvin has rapidly deteriorated
overnight. The low-level center, if it still exists, appears to be
located inland over the Mexican state of Oaxaca, while the mid-level
center has moved westward along the immediate coast of southern
Mexico. It is quite possible that the low-level center has
dissipated, but advisories will continue until visible satellite
imagery provides a better assessment later this morning.
Surface observations and earlier scatterometer data confirm
that Calvin has quickly weakened. Rapid weakening should continue
this morning and Calvin is expected to dissipate over the
mountainous terrain of southern Mexico later today.
Calvin and its remnants are expected to produce additional heavy
rainfall over portions of southern Mexico for another day or so.
These rains are likely to produce life-threatening flash flooding
and mudslides.
