Drought has identified water conditions in the western United States in recent years. this year , conditions It looks particularly dry in the southwest of the United States, according to the National Oceanic Administration, atmosphere and the integrated national drought system.
Organizations issued a a report Earlier this month, it shows the circumstances with ice water throughout the West. the a report Dry conditions were concluded in the southwest and produced the “deep snow deficit”.
What is happening?
From the west of the United States, 62 % NOAA and NIDIS stated that the snowwater conditions that are less than the average of this winter. It included the dryer areas northwest of Montana, eastern Wyoming, central and southern Utah and southwest of Colorado, while Arizona and New Mexico were the lowest rain.
Arizona and New Mexico recorded less than 50 % One of the natural snowwater conditions except for two monitoring stations. Some of these stations – such as the Verdi basin and the small Colorado basin in Arizona – witnessed less than 8 % and 17 % of normal cases, respectively. the a report The return of southwestern snow was described as “deep”, which could be “decisive” for water supply in the region.
Why do dry conditions concern?
Dry winter winter in Arizona and New Mexico will reduce southwestern water supply in spring and summer. The reclamation office expects a flow to Lake Powell – which Supplies Water for societies in Arizona, Nevada and California – in 67 % Normal from April to July.
This winter does not represent the first snowy pillar southwest. Lake Powell has witnessed “long -term drought” and lower water levels since 2002, according to Defenders of Western resources. Organization Described The ice pillar in the water gatherings in Lake Powell as “rarely” is higher than the average.
This decrease in snowy water conditions results from climate changes instead of weather. High temperatures make dehydration more common and more severe Noa. Warmer temperatures NoaAllow the atmosphere to keep more moisture before falling like rain or snow.
Rain can reduce water resources, such as Lake Powell, and affect other weather events, such as forest fires. Increasing the risk of forest fires in the southwest to June, predicts National Center for Fires.
What is done about these conditions?
Drought lasts due to high temperatures, but we can reduce its effect. Education and work regarding Climate issues It can attract attention to them. Legislation related to these issues, such as Drought emergency plan This runs and preserves water in Lake Powell, can prevent negative consequences from it.
Dry landscape success, such as Lake Urmia in Iran, gives a reason for hope. Other projects, like them to improve drinking water in Florida, help both environments and societies affected by drought.
