Homeland Security Threat Level: YELLOW (ELEVATED)

Significant National Weather

West
Rain and higher elevation snow is expected for portions of the Pacific Northwest beginning this evening and continuing into Wednesday, but is expected to remain north of the Central Great Basin. The wintry mix of rain and snow that has been impacting Southern California and the Desert Southwest will gradually come to an end today. Temperatures in the Southwest will be below normal with highs in the low 40s.
South
The Gulf Coast will see an increase in rain and thunderstorms today but severe weather is not anticipated. The remainder of the South will remain dry and cool.
Northeast
Lake effect snow will continue for parts of western New York for the next couple of days, with snow accumulations of up to 3 inches. The remainder of the Northeast and Mid-Atlantic regions will remain dry and cool.
Midwest
Cold temperatures will return to region with high temperatures below freezing as far south as Missouri by the end of the week. Ice jams may result from high stream flows and the return to very cold air temperatures. Lake effect snow will produce up to four inches of snow in the Upper Midwest across the Great Lakes Region tonight into Wednesday morning. The Northern Plains will see minor snow accumulations through Friday.

Earthquake Activity

On Jan. 3, 2010, a magnitude 3.3 earthquake occurred at 3:23 p.m. EST, five miles west of Junction, Utah, at a depth of 0.1 miles. This quake followed the 4.6 magnitude temblor in the same location that occurred at 7:06 a.m. EST, earlier the same day. No damage or injuries were reported from either event. These earthquakes are occurring along the Intermountain Seismic Belt (ISB), a zone of north-south-trending seismic activity located primarily in southern Utah. The ISB is characterized by scattered seismicity with locally dense clusters of small to moderate sized earthquakes and event swarms of magnitudes 3 to 4 are common. The largest quake ever reported in this area was a magnitude 6.5 quake that struck near Richfield, Utah in 1901.
