A tale of two record rainfalls: (I have family living near Charleston)

1) From: http://www.bcsnoticias.mx/en-un-solo-dia-llovio-en-la-paz-lo...

La Paz, Baja California Sur (BCS). La Comisión Nacional del Agua dio a conocer los registros de precipitaciones del sábado, y en La Paz, en tan sólo un día llovió más de lo que llueve, en promedio, durante un mes en todo BCS.

De acuerdo al registro, que contempla las precipitaciones del sábado, desde 7:00 a las 18:00 horas, en la Capital de la entidad cayeron 57.5 milímetros (mm) de lluvia; esto, es alrededor de un 14% más de lo que llovió en julio o un 54% más de lo de agosto, 2 de lo meses con más agua en la entidad.

2) As of midday, nearly 20 inches of rain had fallen in parts of South Carolina in the previous 24 hours alone, according to estimates from weather radar. That’s nearly four months of rainfall in a single day, and it exceeds the National Weather Service’s already-dire predictions.

57 mm is only 2 1/4 inches. from the videos I posted on another thread either that rain all came down at once or there was more above the arroyos.

rts551 - 10-4-2015 at 09:06 AM

The average rainfall for a year is 169mm.

Lot of rain, it's sunny, roads are horrible, some homes and cars were flooded, certainly, very little support.

Thanks for the images gnukid- what a mess!

Anyone know how often this level of rain/flooding has happened before in La Paz without a hurricane hitting directly?

I've read about previous floods, but thought it was during hurricanes, and that a dam had been constructed to prevent this amount of water from reaching town.

Those mm ... really look big ... all at once

Everything moving out ok ?

Has that dirt work above helped any ... or made it worse

Gets hard trying to get water to go where ya want it ...

Look at the Mississippi and a few others

Storm arriving earlier in the day in La Ventana, seemed like a normal rainy day.

It did rain gatos y perros yesterday but it was not that unusual. This kind of thing happens in the rainy season every other year or so.

Historically, there have been some serious flooding all over Baja California. The biggest problem the Jesuit and Dominican missionaries had was either drought or flooding. A number of missions had to be rebuilt because of floods.

Typical of a desert area and Baja is considered an offshoot of the Sonora desert. Sometimes, rain creates a tough clay-like surface called caliche. When it next rains, the water cannot soak in and runs off. Result - flooding.

If one takes the time to look around, dry river beds are huge signs of past flooding or heavy run off.

I'm sure DavidK has some more accurate data of past flooding.

Does La Paz even have a storm drain system, or rely on the streets to channel runoff?

Does anybody have a report on the area between La Paz and El Centenario?

The Franciscans were running the Baja missions for 5 years and they considered moving the Mulege mission following the floods of 1770. La Magdalena was the proposed new location.

I don't believe so.
Every time while there during a heavy downpour, all the streets had 6 to 8 inches of running water in no time and it all headed towards the bay.
This is nothing new

Nothing like a state capital lacking infrastructure.

Several years ago there was a very informative posting here about the catastrophic 1976 Hurricane Liza flooding in La Paz. I am sure the map and arroyo pics still have some relevance today.
