Powerful rainstorm hits California, flood risk rises sharply

Arab Weather - The results of the numerical models at the Arab Weather Regional Center indicate the formation of a low pressure system over the waters of the middle of the ocean, moving towards the state of California and gaining sufficient moisture, coinciding with the flow of very cold polar winds towards the center of the low pressure system, as large areas of the state are expected to witness very heavy rainfall and the risk of landslides increases.

Rainstorm to affect California late this month and early next month

Large parts of the state will be affected in the coming days by a rainstorm that will intensify at the beginning of next month, coinciding with the flow of very cold polar winds towards the center of the storm, as large areas of the state are expected to witness very heavy rains accompanied by strong winds and high waves. Snow is also expected to fall in many areas in California, and it is expected that the low pressure and rain will cause an increase in humidity levels in the atmosphere and wet dry plants, thus reducing the risk of fires further.

The risk of floods and torrential rains increases significantly in conjunction with the rainstorm.

After large fires, the layers of soil and vegetation that help absorb water are destroyed. When heavy rains occur after these fires, a layer of ash forms on the ground surface. This layer is impermeable, preventing water from infiltrating the soil as it normally would. Instead of the soil absorbing the water, the water collects on the ground surface, increasing the likelihood of mudslides and flash floods. The ash from the fires acts as a barrier that prevents the soil from absorbing water, which leads to large amounts of water flowing suddenly, causing destruction to infrastructure and natural resources and threatening the affected areas with floods and flash floods.

And God knows best.
