Here we go again - New Orleans flooding

A big weather system is hitting Louisiana. A couple of clickable headlines:

• • As Plaquemines orders evacuation, New Orleans-area leaders hold off amid rising flood concerns
  • Hurricane watch issued in Louisiana as tropical system gains strength in Gulf of Mexico
  • Rainfall floods New Orleans streets, in taste of storm ahead
  • Flooding swamps New Orleans; possible hurricane coming next

From The Weather Channel:

Tropical Storm Barry Likely to Form in Gulf of Mexico, May Become a Hurricane; Flooding, Surge, Wind Threats Ahead

• • A broad area of low pressure is likely to develop in the northern Gulf of Mexico.
  • It will eventually strengthen into Tropical Storm Barry, and become a hurricane before landfall this weekend.
  • Tropical storm, hurricane and storm-surge watches could be issued for a portion of the northern Gulf Coast on Wednesday.
  • The track of future Barry remain a bit uncertain.
  • A major threat of rainfall flooding is in play over the northern Gulf Coast and lower Mississippi Valley.
  • Storm surge flooding is also likely, particularly to the east of future Barry's track.

And the cone - from the National Hurricane Center:

Time to batten down the hatches. It will be interesting to see if all the post-Katrina money was well spent.
