Slight fluctuations in intensity are possible tonight and Sunday
before landfall in Belize, with weakening expected after landfall.
Sara is expected to dissipate Sunday night or Monday as it crosses
the southern portion of the Yucatan Peninsula.

RAINFALL: Through early next week, rainfall amounts of 15 to 25
inches with isolated storm totals around 35 inches area expected
over northern Honduras. This rainfall will lead to widespread areas
of life-threatening and potentially catastrophic flash flooding and
mudslides, especially along and near the Sierra La Esperanza.

Elsewhere across the rest of Honduras, Belize, El Salvador, eastern
Guatemala, western Nicaragua, and the Mexican State of Quintana Roo,
Tropical Storm Sara is expected to produce 5 to 10 inches of rain
with localized totals around 15 inches through early next week. This
will result in areas of flash flooding, perhaps significant, along
with the potential of mudslides.
