La Crosse Technology TX5U B. Weather Tendency Arrows, C. Storm Warning, Comfort Level Indicator

Weather Tendency Arrow

Sunny—indicates that the weather is expected to improve (not that the weather will be sunny).

Sun with Clouds—indicates that the weather is expected to be fair (not that the weather will be sunny with clouds).

Clouds with Rain—indicates that the weather is expected to get worse (not that the weather will be rainy).

The weather icons change when the unit detects a change in air pressure. The icons change in order, from “sunny” to “sun with clouds” to “clouds with rain” or the reverse. It will not change from “sunny” directly to “clouds with rain”, although it is possible for the change to occur quickly. If the syumbols do not change, the weather has not changed (or the change has been slow and gradual).

B. WEATHER TENDENCY ARROWS

LCD 4 also displays the weather tendency arrows. There is one that points up (on the left side of the

LCD) and one that points down (on the right side of the LCD). These arrows reflect current changes in the air pressure. An arrow pointing up indicates that the

air pressure is increasing and the weather is expected to improve or remain good, and arrow pointing down indicates that the air pressure

is decreasing and the weather is expected to become worse or remain poor. No arrow means the pressure is stable.

C.STORM WARNING

A storm can be expected if there is a drop of 4 hPa or more in less than 6 hours. The clouds with rain icon will be displayed and the tendency arrow that points down will be flashing—indicating the storm warning feature has been activated. The flashing will stop when the air pressure stabilizes or begins to rise.
