## CONCLUSIONS

**Transversal cooperation among primary information providers is highly convenient.**
- In the del Plata Basin, the following issues are present:
** **High incidence of **mesoscal****e** **convectiv****e**** s****y****stems**** (MCS)**, of very low predictability. This seriously limits the forecasts to daily horizons.** **
**Uncertainty due to sparseness of the hydrometeorological network**. Sustainable networks should be installed.
**Urban areas have been developed in inundable riparian areas**. Growing population increases the vulnerability.
