Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
70 The river exceeds the levees - flooding is widespread, disastrous, and life threatening -
65 The river is approaching the top of the levees - residents should be prepared to evacaute rapidly to several tens of miles from the lower Rio Grande channel as emergency officials direct - persons in the flood plain should monitor the latest stage and forecast levels of the river continuously.
58 Major flooding covers the flood plain inside the levees-threatens lowest residences in Brownsville and Matamoros - persons vulnerable to lowland flooding should move equipment to higher ground and monitor the level of the river especially if heavy rain conditions develop.
56 Moderate lowland flooding inside the levees reaches lowest secondary roads and low bridges
55 Minor lowland flooding reaches into the lowest sections of the flood plain inside the levees with no significant damage
44 The river will exceed the lowest banks of the lowest sections inside the levees
