I tried loading this and got annoyed by the popup. So I used Ctrl-U to view the source, copied it into a file on my local machine and used "lynx -dump" to create a text version.

Here it is, minimally tidied by hand.

   Critical weather radar is out of service — which may explain weirdness in
   forecasts

   Hikers make their way along Mount Umunhum Trail to the summit in
   September 2017. The hiking area near Los Gatos is also home to critical
   weather radar, which forecasters at the National Weather Service Bay
   Area use to track storms. This radar has been offline since Saturday,
   and is causing forecast accuracy issues.

   A Bay Area weather radar system that provides critical data
   meteorologists use to track incoming storms has been out of service
   since midday Saturday.

   Rain splashing across weather apps Saturday night seemed to vanish
   after the radar, which sits atop Mount Umunhum in the Santa Cruz
   Mountains, went offline. Weather service meteorologist Dylan Flynn said
   the office was “handicapped” as rain and thunderstorms continued Sunday
   and forecasters were unable to examine the structure of individual
   storm cells.

   The National Weather Service operates 160 weather radars across the
   U.S. and its territories. Radar detects the size and motion of
   particles in rain, snow, hail and dust, which helps meteorologists
   track where precipitation is falling. Radar can even indicate the
   [84]presence of a tornado, such as the one that hit Scotts Valley in
   December.

   As of Monday morning, there was no clear estimation of when the radar
   might be fixed, but meteorologists were hopeful for a return to service
   Tuesday. [85]Rain is expected to return to the Bay Area early
   Wednesday, which could pose additional problems if the radar is not
   operable.

   “The biggest hindrance to us is not necessarily the forecast, but it’s
   to warning operations if any of these cells develop thunderstorms,”
   Flynn said. “If there’s anything that turns severe or starts producing
   hail or rotation and we need a tornado warning, we really won’t be able
   to tell that to the same degree we typically do when our radar works.”

     The KMUX radar is down until further notice (UFN). Technicians have
     been notified, but time of restoration is unknown. Some coverage is
     available from neighboring radars at Eureka, Beale AFB, Sacramento,
     Hanford, and Vandenberg SFB. [86]pic.twitter.com/JNSHlcuDlA

   An expensive broken part in the radar needed to be specially ordered.
   It was not clear whether the ongoing freeze in some government spending
   is causing any delay in ordering or shipping the part. A National
   Weather Service spokesperson did not immediately respond for a request
   to comment.

   Radar outages are not unusual. Minor repairs, such as air conditioning
   fixes, can quickly be performed by electronics technicians. But major
   repairs can last days or even weeks.

   The Monterey weather service office has three electronic technicians
   who do maintenance on radar, [88]rain gauges and other equipment. All
   three are probationary employees in their first year of service, but
   were not a part of the [89]layoffs that took place Thursday.

   Another weather radar, in San Diego, went offline Saturday morning and
   remains out of service until further notice. The weather service said
   it was awaiting new parts.

   During a radar outage, the weather service typically relies on public
   precipitation reports through social media and phone calls. But the
   phone lines at the Monterey weather service office have been down since
   early Sunday morning, with no estimated time for repair.

   The facilities technician, who served several weather service offices
   around the region, was included in Thursday’s layoffs. It was not
   immediately unclear whether the facilities technician’s
   responsibilities included fixing phone lines, but a [90]weather service
   document describes the job duties as “necessary to install or repair
   structures, cable and equipment.”

   Marin Headlands near Sausalito during a brief break from the rain in
   February.

   “Reports from the public are huge at all times, but especially when
   we’re losing our primary data source for warning operations,” Flynn
   said. “There are a lot of people who don’t have social media that call
   us, and we weren’t getting those calls.”
