A hurricane warning has also been issued for the northeast TX/southwest LA Coast, with maximum sustained winds estimated at 70 knots! The center of Humberto can be seen clearly on Houston, TX radar, which shows a fairly compact but intense storm. Shown above is a loop showing the landfall of Humberto.

FORECASTER MAINELLI/AVILA
Here is a satellite image of Hurricane Humberto from peak intensity, at around 1:30 am CDT. The Weather Channel reported frequent lightning with the eyewall of Humberto! It is likely that if Humberto had more time over the warm Gulf of Mexico waters, it could have become a rather significant hurricane.
