Tropical Depression TWO -- TX/MX Threat

Tropical Depression TWO has formed in the Gulf of Mexico from the system we've been keeping an eye on the last few days. National Hurricane Center just put out an advisory on this at 11PM ET, and will continue to send out updates every 3 hours.


Quick info from the Hurricane Center:

LOCATION...23.9N 93.9W
ABOUT 265 MI...425 KM ESE OF BROWNSVILLE TEXAS
ABOUT 245 MI...395 KM E OF LA PESCA MEXICO
MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/HR
PRESENT MOVEMENT...NW OR 310 DEGREES AT 14 MPH...22 KM/HR
MINIMUM CENTRAL PRESSURE...1005 MB...29.68 INCHES

A TROPICAL STORM WARNING is in effect for the Texas coast from the mouth of the Rio Grande (Texas/Mexico border) to Baffin Bay, TX.

A TROPICAL STORM WARNING is in effect for the Mexican coast from the mouth of the Rio Grande (Texas/Mexico border) to Rio San Fernando, Mexico.

Here is the projected path of TD Two from the hurricane center:

Current satellite image (click here for most recent):


TD 2, potentially to become Tropical Storm Bonnie, will take a path almost identical to Hurricane Alex last week. Landfall is expected sometime tomorrow evening (between 4 and 7PM) with maximum winds of 45 MPH (barely a tropical storm).

The main threats with this system, as is expected with all landfalling systems, will be life threatening rains, tornadoes (especially on the Texas side of the storm), and winds.

Everyone in the affected area needs to stay alert for rapidly changing conditions. Even the weakest tropical storms can be killers.
