Title: ناس كلفورنيا...اعملوا حسابكم.

بحكم شغلى جانى ايميل بيقول الاتى:
عاصفة ( او اتنين) جايه فى الطريق يوم الاحد. ح تستمر لحدى الاحد البعده. العلماء بيقولوا انها ح تكون حدث فى كلفورنيا.

بس عاوزه اقول ليم حضروا اكل معلب و مياه و صندوق الاسعافات الاوليه و املوا العربات بنزين و كلموا جميع افراد الاسرة يعملوا شنو فى حالة حدوث فيضانات...لانها محتملة جدا جدا.

و ده جزء من الايميل:
Quote: Currently, the strong El Nino is reaching its peak in the Eastern Pacific, and now finally appears to be exerting an influence on our weather. The strong jet has been apparent for quite some time out over the open water, but the persistent block had prevented it from reaching the coast. Now that the block has dissolved completely, a 200+ kt jet is barreling towards us. Multiple large a"nd powerful storm systems are expected to slam into CA from the west and northwest over the coming two weeks, all riding this extremely powerful jet stream directly into the state. The jet will itself provide tremendous dynamic lift, in addition to directing numerous disturbances right at the state and supplying them with an ample oceanic moisture source. The jet will be at quite a low latitude over much of the Pacific, so these storms will be quite cold, at least initially. Very heavy rainfall and strong to potentially very strong winds will impact the lower elevations beginning late Sunday and continuing through at least the following Sunday. This will be the case for the entire state, from (and south of) the Mexican border all the way up to Oregon. Above 3000-4000 feet, precipitation will be all snow, and since temperatures will be unusually cold for a precipitation event of this magnitude, a truly prodigious amount of snowfall is likely to occur in the mountains, possibly measured in the tens of feet in the Sierra after it’s all said and done. But there’s a big and rather threatening caveat to that (discussed below).Individual storm events are going to be hard to time for at least few more days, since this jet is just about as powerful as they come (on this planet, anyway). Between this Sunday and the following Sunday, I expect categorical statewide rainfall totals in excess of 3-4 inches. That is likely to be a huge underestimate for most areas. Much of NorCal is likely to see 5-10 inches in the lowlands, with 10-20 inches in orographically-favored areas. Most of SoCal will see 3-6 inches at lower elevations, with perhaps triple that amount in favored areas.
This is where things get even more interesting, though. The models are virtually unanimous in “reloading” the powerful jet stream and forming an additional persistent kink 2000-3000 miles to our southwest after next Sunday. This is a truly ominous pattern, because it implies the potential for a strong Pineapple-type connection to develop. Indeed, the 12z GFS now shows copious warm rains falling between days 12 and 16 across the entire state. Normally, such as scenario out beyond day seven would be dubious at best. Since the models are in such truly remarkable agreement, however, and because of the extremely high potential impact of such an event, it’s worth mentioning now. Since there will be a massive volume of freshly-fallen snow (even at relatively low elevations between 3000-5000 feet), even a moderately warm storm event would cause very serious flooding. This situation will have to monitored closely. Even if the tropical connection does not develop, expected rains in the coming 7-10 days will likely be sufficient to cause flooding in and of themselves (even in spite of dry antecedent conditions).
In addition to very heavy precipitation, powerful winds may result from very steep pressure gradients associated with the large and deep low pressure centers expect ed to begin approaching the coast by early next week. Though it’s not clear at the moment just how powerful these winds may be, there is certainly the potential for a widespread damaging wind event at some point, and the high Sierra peaks are likely to see gusts in the 100-200 mph range (since the 200kt jet at 200-300 mb will essentially run directly into the mountains at some point). The details of this will have to be hashed out as the event(s) draw closer.
In short, the next 2-3 weeks (at least) are likely to be more active across California than any other 2-3 week period in recent memory. The potential exists for a dangerous flood scenario to arise at some point during this interval, especially with the possibility of a heavy rain-on-snow event during late week 2. In some parts of Southern California, a whole season’s worth of rain could fall over the course of 5-10 days. This is likely to be a rather memorable event. Stay tuned.

لو صاحب العاصفة هطول أمطار يكون الخوف من الـ Landslide
(الإنزلاق أو الإنهيار الأرضي) خاصة مع جبال كاليفورنيا الترابية الهشة.
الله يستر ويسلم الجميع.

سلامات Elawad
شكرا على الدعوات لطيبات

سلامات عزيز عيسى
كلفورنيا رغم جمال الجو لكن مصايبها كتيرة.
الفيضانات و الزلازل و الانهيارت.
السنة دى شكلها الفيضانات ح تكون برناامج. خاصة فى الشمال
ربنا يستر

This is a weather forecast from NOAA that was sent to the Marine Mammal Center today
NOAA (as you might know ) is The National Oceanic and Atmospheric Administration
www.noaa.gov/

The Marine Mammal Center is a private non-profit U.S. organization centered on rescue, rehabilitation, environmental research and education regarding marine mammals such as cetaceans and seals.

عشان كده احتمال الموضوع يكون ما انتشر لسه فى التلفزون و الاعلام. و يكون فى الاوساط العلمية بس

سلامات هدى ...

غريبه ان الناس فى LA ما قاعده تتكلم عن الموضوع.
لانى فتحت الان Los Angeles Weather فى النت و لقيت انه فى Severe Weather Alert

http://weather.yahoo.com/united-states/california/los-angeles-2442047/


و ده هو:

...A MAJOR PATTERN CHANGE IS EXPECTED NEXT WEEK WITH THE POTENTIAL
FOR EXCESSIVE RAINFALL AND STRONG WINDS...

A MAJOR CHANGE IN THE UPPER LEVEL PATTERN IS EXPECTED TO BEGIN ON
SUNDAY AND CONTINUE THROUGH NEXT WEEK. A VERY POWERFUL WEST TO
EAST JET STREAM SAGGING SOUTHWARD THROUGH THE PACIFIC WILL BREAK
DOWN THE PERSISTENT RIDGE ACROSS THE WEST COAST. THIS WILL ALLOW
STORM SYSTEMS TO TRACK INTO SOUTHERN CALIFORNIA WHILE MAINTAINING
A RICH SOURCE OF SUBTROPICAL MOISTURE.

CONFIDENCE IS GROWING THAT SIGNIFICANT AND POSSIBLY EXCESSIVE
RAINFALL WILL OCCUR OVER SOUTHWESTERN CALIFORNIA FROM SUNDAY THROUGH
MOST OF NEXT WEEK...BUT THE EXACT DETAILS OF TIMING ARE STILL
UNCLEAR. AT THIS TIME...IT APPEARS THERE WILL BE THREE OR FOUR
SEPARATE STORM SYSTEMS MOVING INTO THE AREA BETWEEN LATE SUNDAY AND
FRIDAY. FOR THE ENTIRE WEEK...THERE IS THE POTENTIAL FOR RAINFALL
TOTALS OF 4 TO 8 INCHES IN COASTAL AND VALLEY AREAS...AND 8 TO 16
INCHES IN THE FOOTHILLS AND MOUNTAINS. LOCAL RAINFALL AMOUNTS OVER
20 INCHES WILL BE QUITE POSSIBLE ACROSS FAVORED SOUTH FACING COASTAL
SLOPES.

THE STRONG SOUTHERLY WINDS THAT ARE PROJECTED AT TIMES NEXT WEEK
COULD BRING SIGNIFICANT OROGRAPHIC ENHANCEMENT OF RAINFALL ACROSS
SOUTH FACING SLOPES. RAINFALL RATES OF AROUND ONE INCH PER HOUR
WILL BE POSSIBLE DURING THE PEAK TIMES OF HEAVIEST RAINFALL...WHICH
CURRENTLY APPEAR TO BE MONDAY...AS WELL AS LATE WEDNESDAY INTO
THURSDAY. EARLY INDICATIONS ALSO SHOW THE POSSIBILITY OF EMBEDDED
THUNDERSTORMS AT TIMES DURING THE WEEK...WHICH COULD BRING LOCALIZED
RAINFALL RATES IN EXCESS OF ONE INCH PER HOUR.

THE LARGE AMOUNT OF EXPECTED PRECIPITATION...AS WELL AS THE
POTENTIAL FOR HIGH INTENSITY RAINFALL...WILL BRING A SIGNIFICANT
THREAT OF FLASH FLOODING AND DEBRIS FLOWS...ESPECIALLY TO THE RECENT
BURN AREAS. AS SOILS BECOME MORE SATURATED THROUGH THE WEEK...THERE
COULD ALSO BE AN INCREASED RISK OF URBAN AND SMALL STREAM FLOODING. IF
THE STRONG STORM MATERIALIZES FOR THE LATE WEDNESDAY INTO THURSDAY
TIME FRAME...THERE COULD ALSO BE SOME MAIN STEM RIVER FLOODING
CONCERNS.

SNOW LEVELS ARE GENERALLY EXPECTED TO RANGE BETWEEN 4000 AND 6000
FEET NEXT WEEK. AS STRONG SOUTHERLY WINDS PRECEDE THE STRONG
SYSTEMS...SNOW LEVELS SHOULD BRIEFLY RISE ABOVE 6000 FEET ON
MONDAY AND WEDNESDAY. THERE IS THE POTENTIAL FOR SIGNIFICANT SNOW
IN THE MOUNTAINS NEXT WEEK...WITH SEVERAL FEET OF NEW SNOW POSSIBLE
AT RESORT LEVELS ABOVE 6000 FEET.

AT THIS TIME...THE STRONGEST SOUTHERLY WINDS APPEAR TO BE
WEDNESDAY...WHEN THERE WILL BE THE POTENTIAL FOR WIDESPREAD GALE
FORCE WINDS ACROSS THE COASTAL WATERS AND DAMAGING WINDS ACROSS
PORTIONS OF SOUTHWEST CALIFORNIA.

AS THESE STORMS MOVE INTO THE AREA NEXT WEEK...THEY WILL ALSO BRING
THE POTENTIAL FOR A LONG DURATION OF HEAVY SURF CONDITIONS AND DANGEROUS
RIP CURRENTS TO THE LOCAL BEACHES. THE COMBINATION OF STRONG WINDS AND
HIGH SEAS COULD ALSO BRING SOME COASTAL FLOODING ISSUES...ESPECIALLY
NEAR TIMES OF HIGH TIDE.

RESIDENTS OF SOUTHWESTERN CALIFORNIA ARE URGED TO STAY TUNED FOR THE
LATEST INFORMATION ON THESE POTENTIALLY STRONG STORM SYSTEMS.
