Hurricane Lowell is forecast to pass west of Kauai today. Impacts such as high surf and heavy rain could impact all of the islands. A Hurricane Warning is in effect for Kauai, Niihau and the surrounding coastal waters. Sweltering heat remains across the South-Central Plains and Lower/Middle Mississippi Valley, as well as in the Southwest this week with limited nighttime relief. Read More >

Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio - HF (high frequency) radio propagation can fade at higher latitudes.
Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state.
