    Special Weather Statement - 9:41am Tue Oct 13 2026

    ...HEAVY RAIN AND GUSTY WINDS THURSDAY INTO WEEKEND...

    Thursday into the weekend, a series of low pressure systems will
    move toward Southeast Alaska, bringing widespread moderate to heavy
    rainfall. Strong winds are also expected for coastal and southern

    system are still being refined, confidence is continuing to increase
    that this will be a more impactful system for Southeast Alaska.

    For the northern and central Panhandle, while rivers are expected to
    rise no flooding is anticipated at this time.

    Stay tuned to weather.gov/juneau as we continue to monitor the
    developing situation and update our forecast.
