Dangerous, Multipronged Storm Strafing Central/Northern California

What may become known as the President’s Day Storm of 2017 barreled into the San Francisco Bay area on Monday morning. The core of the storm was an atmospheric river roughly 75 to 100 miles wide, pointing a firehose of moisture toward vulnerable foothills and urban areas. With soils already sodden, the risk of flash flooding was high, and the tail end of the storm promised to bring ferocious winds into the area that could knock out power for many thousands of resi...

No Rest: Another Round of Intense Rains Heading for Central and Northern California

By: Bob Henson, 16:08 GMT dnia 19-luty-2017

While southern California tries to dry out from Friday’s watery onslaught, yet another atmospheric river will be pointed at central and northern California from late Sunday through Monday, exacerbating the woes of what’s already been a record-wet winter to date across the northern Sierra. Precipitation totals of 10” or more are possible early this week across parts of the Feather River watershed feeding into Lake Oroville. This is bound to push lake levels tow...

The epic assault of the winter of 2016 - 2017 on California continued on Friday morning as torrential rains, damaging winds and huge waves from a massive and powerful Pacific storm system pounded the Golden State. Carrying with it an “atmospheric river” of moisture originating in the subtropics near Hawaii, Friday’s storm was most dangerous because of its heavy rains. According to the National Weather Service in Oxnard, California, Friday and Saturday could b...

By: Jeff Masters and Bob Henson, 17:38 GMT dnia 16-luty-2017

January 2017 was the planet's third warmest January since record keeping began in 1880, said NOAA's National Centers for Environmental Information (NCEI) on Thursday. Along with NOAA, NASA also rated January 2017 as the third warmest January on record. The only warmer Januarys were 2016 (highest) and 2007 (second highest). Global ocean temperatures during January 2017 were the second warmest on record, and global land temperatures were the third warmest on record. G...

This is February? 80°F in Denver, 99° in Oklahoma, 66° in Iceland, 116° in Australia

By: Bob Henson, 16:17 GMT dnia 14-luty-2017

The strong, recurrent Pacific jet stream that’s been delivering massive amounts of rain to California has also been pushing mild Pacific air downslope off the Rockies and eastward, keeping the southern two-thirds of the U.S. absurdly warm for early February. From New Mexico to Virginia southward to the Gulf Coast, trees and shrubs are budding out en masse up to three weeks ahead of schedule (see Figure 1). In Texas, Dallas-Fort Worth recorded its last freezing tem...
