Drought update Feb 6 2014

The high pressure system off of California that had maintained the drought conditions on the Pacific coast has broken down. An atmospheric river has hit central to northern California; how much of the region’s drought conditions will weaken in the west from this event–time will tell. In the south, the stronger drought conditions are slowly returning. The rest of the country is unchanged or improving.

For statistics for each region, see below.

Drought update Jan 23 2014

This last week was for the lower 48 states was relatively quite of statistical changes at Drought Monitor.

The biggest change was in Louisiana.

Week Date Nothing D0 D1 D2 D3 D4
Current 1/21/2014 48.66 45.95 5.39 0.00 0.00 0.00
Last Week 1/14/2014 84.28 15.72 0.00 0.00 0.00 0.00

However, the drought out West, though not “expanding” or “intensifying”–the effects are starting to truly set in. Here are some articles from the last couple of days to show what is going on.

California

Governor Brown has declared a state of emergency

Speaker of House has gone out to California for a Drought Bill

Historic California drought called a red flag for future of US (+video)

California drought: Scientists puzzled by persistence of blocking ‘ridge’

Oregon

Oregon Cascades snowpack facing drought

Douglas County drought goes from moderate to severe

There is a  chance of rain for Oregon next 10 days:

Portland on the 28th 50% and 31st 30%
Eugene on the 28th 40% and 30th 30% and 31th 60%
The weather can shift and change rapidly–so by the 28th it could be have 0% of rain or it could be “back to normal” here in Oregon.
(I am not including days with only 10% chance)

Next update is the 30th of Jan.

Hope the is a break in the drought out west, especially in California.

Defining Droughts

There are weekly updates from Drought Monitor from the University of Nebraska in Lincoln and I will be commenting on this topic regularly; I thought would be good idea to summarize in short on what a drought can be.

Droughts are natural and erratically occurring events that can happen anywhere around the world. It happens when there is a large-scale disruption with the global circulation of the atmosphere. Droughts are from the result of a shortage of precipitation over variable time periods and areal extents. The effects from lack of rainfall on the day-to-day use for needs of human and nature can create a natural disaster or hazard. Therefore, many disciples examine the causes and effects from droughts, like: geography, environmental science and studies, ecology, hydrology, meteorology, climatology, dendroclimatology, pedology, geology, and agriculture or horticulture.
