A potentially dangerous weather event is unfolding for Thursday.

Good messages from NWS, especially on having a shelter plan. Very important to monitor the following Thursday:
* Updates on storm timing. Right now we think 7 to 11p, but could shift earlier (or later)
* Watches/warnings that may be issued

A potentially dangerous weather event is unfolding for Thursday. The threats are damaging wind gusts, tornadoes & heavy rain. Everyone should make sure they have a way to receive warnings & get to shelter quickly should severe weather threaten your neighborhood tomorrow evening.

2. 'Potentially dangerous severe weather event' predicted for Washington region Halloween night

‘Potentially dangerous severe weather event’ predicted for Washington region Halloween night

An intense line of storms is expected to barge through the Washington region Halloween night. The squall line is likely to arrive suddenly, with a burst of rain and strong to even damaging winds. A few brief tornadoes are not out of the question.

“All the ingredients remain in place for a potentially dangerous severe weather event tonight," wrote the National Weather Service office serving the Washington region.

Models are in reasonably good agreement that these storms will reach the Washington region after dark, between 7 and 11 p.m. from west to east. For Halloween trick-or-treaters, the safest plan of action is to be home by dark, especially if you live west of Interstate 95. For anyone staying out after dark, have a safe place to seek shelter quickly, if needed.

Here is our best estimate on storm arrival times, by area:

• Interstate 81: 6 to 7:30 p.m.
• Frederick, Loudoun and Fauquier counties: 7 to 8:30 p.m.
• Howard, Montgomery, Fairfax, Prince William and Stafford counties: 8 to 9:30 p.m.
• Interstate 95, the District, the Beltway, Prince George’s and Charles counties: 8:30 to 10:00 p.m.
• Anne Arundel and Calvert counties: 9:30 to 11 p.m.



Estimate of approximate timing of storms from National Weather Service. We believe this is a reasonable prediction. (National Weather Service)
