This information about the flooding is from my friend Napolean.

184 people have died.
100 are still missing
2000 houses destroyed
15,000 refugees in shelters
30% of corn, beans and coffee crops destoyed. This means high prices and hunger in many places.
100 roads destroyed
23 bridges destroyed
5 major/important bridges destroyed
one of those bridges is on the road to la palma, puente colima
4000 heads of livestock, cows, dead. This means no milk

the main destruction happened in San Salvador, as city and department, San vicente, La libertad, La Paz, Cuscatlan

roads are still blocked as consequence of landslides.

in 5 hours, 355 ml of rainfall hit certain areas. To give you an idea: that would be a 1/5 of the rain we get in 6 months.

in some areas towards the coastline, the rivers went from 1 mt deep to 10 mts in depth.

In San Vicente, three cities were wiped out. the landslide destroyed them when it cut right through them.

In total 150,000 cubic meters of rock and mud are being removed by the population and the government in those towns.
