Narrative:

Departed ory runway 25 on LGL7P. No obvious WX at airport or on departure path noted prior to takeoff. No WX forecast or reported in area. Stratus level west of airport noted at 4000 ft or so, broken layer. No WX advisory from ATC. Crew busy flying departure procedure in raw data so as to fully comply with SID and noise concerns. Upon breaking through stratus layer and turning on to 130 degree radial to rbt line of twring cumulo nimbus noted in a semicircular arc from southwest to northeast. Tops perhaps 12000 ft. WX radar showed band of rainshowers. Due to low tops and narrow nature of band, coupled with lack of alternatives, we penetrated the clouds. Encountered the heaviest precipitation I have ever experienced in my career. Selected flight ignition. First officer was flying aircraft and continued to do so very well manually. Experienced possible static discharge. Moderate turbulence. Noise on flight deck too loud to hear radio xmissions. In WX indeterminate time, I guess 2 mins. Upon exit from north side of WX, advised paris departure not to send other aircraft on this departure. Performed visual inspection of aircraft pylons, cowl, etc. No cockpit anomalies. Advised dispatch via ACARS of WX encountered and advice not to send subsequent flts this way. Emphasis: no warning to flight crew from any source. I remember conversations on frequency in french. Whether this was concerning WX I cannot say, but possible. Workload on 2 man crew made it difficult to see. I feel I am as cautious as possible when it comes to severe WX. I was completely blindsided by this encounter. Although postflt inspection by maintenance showed no problems and no injuries were suffered aboard, I realize the outcome could easily have been much worse. While the buck clearly stops with the captain, the support was not here -- nor sufficient information to take necessary action. Language clearly a problem. Adherence to difficult SID a factor. While this is a foreign destination I would expect better information in western europe.

Title: B767 FLC ENCOUNTERED UNRPTED HVY RAIN DEPARTING ORY.

Narrative: DEPARTED ORY RWY 25 ON LGL7P. NO OBVIOUS WX AT ARPT OR ON DEP PATH NOTED PRIOR TO TKOF. NO WX FORECAST OR RPTED IN AREA. STRATUS LEVEL W OF ARPT NOTED AT 4000 FT OR SO, BROKEN LAYER. NO WX ADVISORY FROM ATC. CREW BUSY FLYING DEP PROC IN RAW DATA SO AS TO FULLY COMPLY WITH SID AND NOISE CONCERNS. UPON BREAKING THROUGH STRATUS LAYER AND TURNING ON TO 130 DEG RADIAL TO RBT LINE OF TWRING CUMULO NIMBUS NOTED IN A SEMICIRCULAR ARC FROM SW TO NE. TOPS PERHAPS 12000 FT. WX RADAR SHOWED BAND OF RAINSHOWERS. DUE TO LOW TOPS AND NARROW NATURE OF BAND, COUPLED WITH LACK OF ALTERNATIVES, WE PENETRATED THE CLOUDS. ENCOUNTERED THE HEAVIEST PRECIP I HAVE EVER EXPERIENCED IN MY CAREER. SELECTED FLT IGNITION. FO WAS FLYING ACFT AND CONTINUED TO DO SO VERY WELL MANUALLY. EXPERIENCED POSSIBLE STATIC DISCHARGE. MODERATE TURB. NOISE ON FLT DECK TOO LOUD TO HEAR RADIO XMISSIONS. IN WX INDETERMINATE TIME, I GUESS 2 MINS. UPON EXIT FROM N SIDE OF WX, ADVISED PARIS DEP NOT TO SEND OTHER ACFT ON THIS DEP. PERFORMED VISUAL INSPECTION OF ACFT PYLONS, COWL, ETC. NO COCKPIT ANOMALIES. ADVISED DISPATCH VIA ACARS OF WX ENCOUNTERED AND ADVICE NOT TO SEND SUBSEQUENT FLTS THIS WAY. EMPHASIS: NO WARNING TO FLC FROM ANY SOURCE. I REMEMBER CONVERSATIONS ON FREQ IN FRENCH. WHETHER THIS WAS CONCERNING WX I CANNOT SAY, BUT POSSIBLE. WORKLOAD ON 2 MAN CREW MADE IT DIFFICULT TO SEE. I FEEL I AM AS CAUTIOUS AS POSSIBLE WHEN IT COMES TO SEVERE WX. I WAS COMPLETELY BLINDSIDED BY THIS ENCOUNTER. ALTHOUGH POSTFLT INSPECTION BY MAINT SHOWED NO PROBS AND NO INJURIES WERE SUFFERED ABOARD, I REALIZE THE OUTCOME COULD EASILY HAVE BEEN MUCH WORSE. WHILE THE BUCK CLRLY STOPS WITH THE CAPT, THE SUPPORT WAS NOT HERE -- NOR SUFFICIENT INFO TO TAKE NECESSARY ACTION. LANGUAGE CLRLY A PROB. ADHERENCE TO DIFFICULT SID A FACTOR. WHILE THIS IS A FOREIGN DEST I WOULD EXPECT BETTER INFO IN WESTERN EUROPE.
