Tropical Cyclone Irina kills 72 on Madagascar
Heavy rains from Tropical Cyclone Irina have killed 72 people on Madagascar and left 70,000 homeless, according to news reports. Irina never reached hurricane strength, but dumped heavy rains on the island over an extended period, February 29 - March 2. The area affected was remote, so the reports of the disaster only today reached the outside world. Irina is the deadliest tropical cyclone of 2012 thus far, and the second deadly storm to affect the island in recent weeks; Tropical Cyclone Giovanna hit the island two weeks ago as a Category 3 storm, killing 35 and leaving 240,000 homeless. Irina is expected to dissipate over cold waters southwest of Madagascar over the next day.

I'll have a new post on Thursday.

Not really. it's on the northern side of the low so it's pretty dry.

Yup!!

Yeah, that's an image you never see during a La-Nina winter across the South. It's best they get it now before the Thermal Ridge builds in from the SW US.
We were friends in High School. Had alot of classes together.
Hi Skye, did you get any rain last evening?
We still need more, and areas out to the west (hill country) need it desperately still. This rain, if the forecast verifies, will be great for the reservoirs, though.
I meant to mention that. 0.17" total so far. I see some showers pulling together & moving west toward shore already.
Tropical Cyclone Advisory #41
TEMPETE TROPICALE MODEREE IRINA (11-20112012)
16:00 PM RET March 8 2012
=====================================
At 12:00 PM UTC, Moderate Tropical Storm Irina (991 hPa) located at 29.5S 40.0E has 10 minute sustained winds of 40 knots with gusts of 60 knots. The cyclone is reported as moving west southwest at 3 knots.
Gale Force Winds

Forecast and Intensity
========================
12 HRS: 29.7S 39.1E - 40 knots (Tempête Tropicale Modérée)
24 HRS: 29.7S 38.0E - 40 knots (Tempête Tropicale Modérée)
48 HRS: 29.2S 36.8E - 35 knots (Tempête Tropicale Modérée)
72 HRS: 25.8S 35.6E - 25 knots (Perturbation Tropicale)
Additional Information
=======================
System drifts slowly westwards and is expected to keep on shifting slowly globally west northwestwards then westwards until Saturday morning on the northern edge of a weak mid level ridge (slower timing in regard of previous forecast). Beyond, high pressures located over South Africa will steer the system north northwestwards. Throughout the forecast period, sea surface temperature remain marginal (25 to 26C). Wind-shear should weaken, as system would lie under an upper level anticyclone, and might remain very weak until Friday afternoon. However, very slow motion on weak oceanic heat content might limit system intensity at the moderate tropical storm stage. Northerly then northwesterly vertical wind shear is expected to increase again Friday night and system is therefore expected to weaken slightly before its landfall that is forecast on Sunday between Maputo and Inhambane.
Inhabitants of the potential landfall area should closely monitor the evolution of Irina within the next few days.
The next tropical cyclone advisory on TC Irina from Seychelles Meteorological Services will be issued at 18:30 PM UTC..

Additional Information
=======================
Tropical storm Koji has been renamed Koji-Joni after crossing longitude 90°E (thus leaving the area of responsibility of TCWC Perth to enter the area of responsibility of RSMC Reunion). This is a consequence of a new procedure adopted in 2010 for the southwest Indian Ocean basin. While the principle of moving towards not renaming named storms coming from the southeast Indian Ocean has been agreed upon, as an interim phase it has been decided to append a hyphenated name from the southwest Indian Ocean naming list to the existing name of the system moving from the southeast Indian Ocean.
System has progressively organize within the last 24 hours hours. It is expected to keep on tracking globally west southwestwards on the northern edge of the subtropical high pressures belt. Over this forecast track, easterly wind shear is expected to keep on existing aloft and intensity variations are expected. From Saturday, system is expected to recurve southwards towards a transiting mid-latitude trough and after a temporarily sheared relax, is expected within Sunday to undergo a new north northwesterly vertical wind shear constraint. System should therefore clearly weaken and its remnants should then been steered westwards by trade winds flow.
The next tropical cyclone advisory on TC Joni from Mauritius Meteorological Services will be issued at 18:30 PM UTC..

VALID 111200Z - 161200Z
...DISCUSSION...
LOW PREDICTABILITY PERSISTS OVER THE DETAILED EVOLUTION OF AN
UPPER-LEVEL TROUGH FROM THE SOUTHWEST INTO THE CNTRL CONUS INTO
EARLY NEXT WEEK. ON THE LARGE-SCALE...GUIDANCE STILL INDICATES
REASONABLE AGREEMENT ON THE NEWD PROGRESSION OF THE TROUGH IN THE
CNTRL CONUS...AS AN UPSTREAM SHORT WAVE TROUGH MOVES ACROSS THE
PACIFIC NW AND SWRN CANADA. STRENGTHENING LOW-LEVEL SLYS OVER THE
WRN GULF COAST TO THE MID-SOUTH SHOULD RESULT IN A N/NEWD EXPANDING
WARM SECTOR. IT IS PROBABLE THAT A CORRIDOR OF AT LEAST MARGINAL
SEVERE POTENTIAL WOULD ACCOMPANY THE EJECTION OF THE UPPER-LEVEL
TROUGH ON SUN/MON D4-5. STILL...GIVEN THE SPATIOTEMPORAL
PREDICTABILITY ISSUES...A 30 PERCENT OR GREATER SEVERE AREA CANNOT
BE RELIABLY IDENTIFIED ATTM.

Actually, the drought isn't surface-based any longer - the surface soil is pretty good. The drought is in the subsurface soil and the lakes now - both are MUCH below normal. What the area needs the most is about an inch to inch and a half per day for a week. Not enough for flooding (guidance is about 2-3" for flooding potential), but enough to get some deep, soaking rains, and solid runoff into the lakes.
*dies* This is two days in a row that i come to this blog and have to stifle the urge to scream like a little girl.
I sure as hell am happy! That is fantastic. Looks like we have some flooding on the way. I wonder how soon they will issue Flood Watches.
I would go with the crawdads lol. Fire ants usually don't start doing that until it is to late (from my experience). Last time we had a significant flood here all the ants were floating around in the water in huge groups.
