May 2016: Shower/Storm Chances To End May

[srainhoutx]

From Jeff


Supercell showing very strong rotation couplet over Washington County heading for northern Waller and S Grimes County.



This cell is likely producing a rain wrapped tornado just NE of Brenham moving ESE at 30mph.



This is a very dangerous tornado situation. Seek immediate shelter in the interior room of a strong building. Protect yourself with pillows and blankets.



Never attempt to out run a tornado in a vehicle and never seek shelter under a freeway overpass.

Another update from Jeff


Excessive rainfall of 5-7 inches over the last 3 hours over Brazos, Madison, northern Grimes Counties.



Widespread significant flash flooding is in progress especially over the Bryan and College Station area. Several small creeks are exceeding their banks and numerous roadways are impassable and water in some subdivisions is nearly into homes.



Large HP supercell likely producing a tornado between Navasota and Brenham is producing nearly 4 inch per hr rainfall rates and this cell will be moving into N Waller and southern Grimes Counties.



Cells continue to fire on SSW moving outflow boundary colliding with strong 30-40kts low level inflow. Additional 1-3 inches is possible on top of the areas that have already seen 5-7 inches this afternoon.



Flash Flooding is in progress and will continue.



Never drive into high water….Turn Around Don’t Drown.



If this activity holds together it could reach NW Harris County by 430pm.

Possible mulit-vortex with this tornado near Navasota.

[jasons2k]

Look like the tornado warning was allowed to expire and severe thunderstorm warning is up now instead.

[DoctorMu]

Tornado sig near Prairie View.

[StormOne]

Rotation seems to be yo-yoing as it heads ESE. Still a very dangerous storm and it may clip far Northern Harris county.

[jasons2k]

Great timing for the BV radar view from HGX to be blipping on and off over there....
