c. 1400UTC to 2200UTC
d. 1400UTC to 0200UTC except for the inter period
Correc answer is C.
Shouldn't the right answer be A or when there is FM, the rain showers are forecast from 1400UTC to 2200UTC
Please clarify the answer.

Hi Spin,
Looks like the correct answer is C.
SH/RA forecast from 1400 until the start of the FM period of 2200.
At a glance, the first line (1402 18020KT 9999 SH/RA SCT030) can easily trick you into picking A due to the FM being on a separate line.

Hope this helps.

Cheers,
Mister W.

Hi Spinrecovery,

MisterW is correct, the showers are only valid until the FM. After 2200 the new set of conditions prevail. One thing to mention though is the TAF as written is slightly incorrect. It should read:

TAF YCWR 121310Z 1214/1302 18020KT 9999 SHRA SCT030
FM 122200 15010KT 9999 BKN010 BKN025
INTER 1215/1221 3000 TS SCT050CB
T 17 16 17 19 Q1002 1003 1004 1005

I don't know if that makes it easier for you to interpret ;-)

Cheers,

Rich

I can't find that TAF in our books or practice exams. Can you let me know where you came across it.

I thought it had a bit of an old fashioned look about it, Richard.

I came across these symbols in the bob tait book while I was studying for MET exam a while back and I cannot recall what are their meanings.
// /// //// If i remember correctly //// due to inadequate information from the sensors or some sort, the cloud base or amount is unknown.
Please help

Richard replied the topic: TAF question

The slashes typically appear in a METAR from an automated station (AUTO). They have the following meanings:

// = no weather sensor available
//// = no visibility sensor available
////// = no cloud detector available.

You'll find them listed in the AIP GEN 3.5 12.20
