Mexico's Katrina

While Hurricane Noel's deadly rampage through the Caribbean was making headlines last week, Mexico experienced one of the worst flooding disasters in its history. Rescue crews are still at work plucking thousands of stranded residents off of rooftops in the state of Tabasco. Over 80% of Tabasco was underwater, and flood waters reached up to residents' rooftops in the capital city of Villahermosa. Up to 900,000 people are homeless in the disaster, which Mexicans are calling their Hurricane Katrina. The number of people dead or missing now stands at 26, due to a new mudslide yesterday that overwhelmed a small village near Villahermosa.

The floods were spawned by heavy rains that fell from a cold front that stalled over the Gulf of Mexico between October 28 and November 1. Satellite estimates of the rainfall show that no more than 7 inches of rain fell over the region during the period, which seems like too little rain to cause the massive flooding observed. It is possible these satellite estimates are flawed. The official rain gauge in Villahermosa reported 2, 81, 7, 0, and 2 inches of rain during the days October 28-November 1, respectively. Presumably, the 81 inches of rain reported October 29 is due to floodwaters inundating the rain gauge. Villahermosa averages 13 inches of rain in a typical October. No new rains have fallen since November 1, and the flood waters are gradually receding.

Disturbance 92L in far eastern Atlantic not a threat
A non-tropical "cut-off" low pressure system near 31N 37W, a few hundred miles southwest of the Azores Islands, is showing signs of becoming more tropical. This system was designated "92L" by NHC this morning. Phase space diagrams from Bob Hart at Florida State University show that 92L started off as a classic extratropical storm that was asymmetrical with a cold core, but the storm has gotten more symmetrical and the core has warmed. Satellite loops show only limited thunderstorm activity near the center of circulation at present, though. Sea Surface Temperatures are about 24° C under 92L, and are considerably cooler than the 26.5° usually needed to get a tropical cyclone going. Wind shear is 30-40 knots, and is expected to stay above 30 knots for the next two days. These factors should keep the storm from developing. The system is expected to turn northeast and move through the Azores Islands Friday or Saturday.

flub.,...

Worked with a guy that was giving a very detailed (probably too detailed for television) description of some severe weather moving through the area. He was getting pretty deep discussing "rear flank development" when the building took a lightning hit. The charge ran through the mic cable which was running up his leg (no wireless mics) and gave him a shock. He gave a short little jump and without missing a beat said, "Whoa, I think I just had a little rear flank development!" I never laughed so hard in my life!!!!

on air flub....

This had most of the state of Michigan laughing for 2 days and a very embarrassed female news anchor who will, in the future, likely think before she speaks. What happens when you predict snow but don't get any... a true story... We had a female news anchor, who the day after it was supposed to have snowed and didn't, turned to the weatherman and asked: "So Bob, where's that 8 inches you promised me last night?" Not only did HE have to leave the set, but half the crew did also! They were laughing so hard!
